JAWA 350 cat.jpg

Pat Brennan's sharing this photo of the JAWA 350, with possible modified carbs and exhaust maybe containing catalysers, in Issue 40 of the JAWA Motorcyclist attracted a lots of reaction.

The JAWA 350 2 stroke twin has been very loyal to the company. Engine design can often be associated with a manufacturer. The Enfield Single cylinder 4 stroke, BMW boxer, Motor Guzzi V engine, Harleys in line V, just some examples. But the 2 stroke is challenged by emissions. MZ dropped their signature 250 single 2 stroke, offered a production range with a 125 Single 4 stroke, 660 Single 4 stroke and 1000cc 4 stroke. Sadly they are no longer in production. JAWA seem to have dropped the idea of rebranding models and looks to be following the same business plan as MZ i.e. 125cc. 660cc. and 1000cc. The one difference is that they are still producing and selling the Loyal 350cc 2 stroke. It cannot be sold in many countries because of emissions but it may well still be the best seller in the JAWA range. So JAWA looking to maintain production of the 350 is understandable.

Most of my experience with 350cc JAWA’s is with the older iron barrel models. I have found them slow to warm up and cool running. I do not think the 350 will run hot enough for a catalyser to be effective. Placing one near the port might be the hottest area but it would strangle the engine. Fuel injection would offer a better solution. The only disadvantage with fuel injection is there can be a slight delay in throttle response. As the JAWA would be going from a single Carb to injector per cylinder this would not be an issue. Also the 2-stroke mix could be more accurately calculated and applied. This would offer an affordable and easy solution. Pat Brennans article in Issue 13 shows what could be done.

If further reduction to emissions is required then the outer mains and center bearings could be lubricated from the gearbox. This would require a little more engineering. But remember JAWA used to lubricate the center bearings separately on the early 634s. I am not suggesting grease nipples but putting in oil ways and reversing seals, making use of the gearbox oil. Roller bearings need a small amount of lubrication. Then the 2T only has to lubricate the big and small end plus the barrel. Less work less oil.

The JAWA 350 has been good to the company; is it time for the company to put something back into the bike that has grown to become their mascot?

Oil Pump Settings

Oil pump setting should be carried out with the free play removed from the cable system by turning the throttle.

F2 pump1

If you simply line up the marks with all the free play in the cables as suggested in the last news letter you have no idea of the pump setting in use. There could be only a mm of free play or there could be 5 mm so as the throttle opens and the engine load increases you could have enough oil or not enough oil. Lining up the marks without taking the free play out of the system is a very inaccurate way of setting the pump, the only certainty is the oil will be correct at idle, which really isn't that critical as there is little load at idle.

Every bike I have sold in the UK has needed the nipple on the pump cable moving along slightly. I simply heat it, move it 5/6 mm along, resolder and crush the bit sticking out the end before the solder hardens as a safety stop. This allows the correct adjustment of the pump without risking taking too much free play out of the throttle cable. The throttle free play is required to avoid any danger of the engine picking up as the bars are turned to full lock.

A guy is driving around the back woods of Montana and he sees a sign in front of a broken down shanty-style house: 'Talking Dog For Sale 'He rings the bell and the owner appears and tells him the dog is in the backyard.

The guy goes into the backyard and sees a nice looking Labrador retriever sitting there. 'You talk?' he asks.b'Yep,' the Lab replies.

After the guy recovers from the shock of hearing a dog talk, he says 'So, what's your story?'

The Lab looks up and says, 'Well, I discovered that I could talk when I was pretty young..I wanted to help the government, so I told the CIA. In no time at all they had me jetting from country to country, sitting in rooms with spies and world leaders, because no one figured a dog would be eavesdropping.'I was one of their most valuable spies for eight years running. But the jetting around really tired me out, and I knew I wasn't getting any younger so I decided to settle down. I signed up for a job at the airport to do some undercover security, wandering near suspicious characters and listening in. I uncovered some incredible dealings and was awarded a batch of medals.'I got married, had a mess of puppies, and now I'm just retired.'

The guy is amazed. He goes back in and asks the owner what he wants for the dog.

'Ten dollars,' the guy says.

'Ten dollars? This dog is amazing! Why on earth are you selling him so cheap?'

'Because he's a liar. He's never been out of the yard'

Crazy Oyibo:

crazy oyibo

Christmas morning brought me unbridled joy. A new Alpinestars Motorcycle Winter Jacket and stuck in the middle of it was a thing called a Kindle. Now most of you might know or even have a Kindle but this gadget was a new one to me. So good on ya Santa, top man!

Anyhow after been made to feel stupid about not knowing what it was from my 16 year old daughter, I found myself searching on Amazon for motorcycle travel books. A quick search found pages of books at very reasonable prices and sure enough some of them were free. So clicking on one of the Freebie’s brought Crazy Oyibo whizzing onto my screen faster than you could lick a stamp.

This is the story of a young Romanian couple who fancied a bit of touring on a Yamaha Tenere 660cc. 55,000km to be exact from Romania to Africa and a full tour of the African continent. Although its fairly well written the translation is poor in places. But hey it was free so why grumble. The trip didn’t start out so well for them as the morning they were about to set off John nearly got wiped out by a car returning from the market with some cheese and tomatoes. Not a very good start as the bike was wrecked and so was his foot. Trip postponed for 9 months until the foot is mended and the engine is swapped out and into another Tenere frame and eventually they set off. The story picks up quite a bit as they reach Morocco and the description of the market food stalls particularly of Marrakesh is very good. I actually want to try the brain of a lamb sometime!!

Crossing the Sahara at 50 degrees C did not pose any problem not even when the drive chain started clattering 300 miles from nowhere. Warnings of unsafe places to camp for the night were completely ignored as the brave John and Ana embraced Africa without fear. Anyway as I read on I kept looking at the bottom of my Kindle and the % read of the novel was heading towards 90% and we were still touring Morocco. Mmmm something not right here me thinks or the last couple of chapters are going to be fairly crammed full of info. Before I know it the book is finished. 100% showing on the bottom of the Kindle so back I go to Amazon to see that I was only after getting Part 1 free! Where is Part 2? It is not released yet. So my friends I have to leave it at that.

Will I be looking for Part 2 in the future? I don’t think so. I have just bought The Long Ride Home the story of an Englishman heading home from Sydney on a Honda 110cc Postman’s bike. Hope this one has a better ending!

Hot and Cold Sex......

After an examination, the doctor said to his patient: 'You appear to be in good health. Do you have any medical concerns you would like to ask me about?'

'In fact, I do.' said the old man. "After my wife and I have sex, I'm usually cold and chilly; and then, after I have sex with her the second time, I'm usually hot and sweaty."


When the doctor examined his wife a short time later he said, 'Everything appears to be fine. Are there any medical concerns that you would like to discuss with me?' The lady replied that she had no questions or concerns. The doctor then said to her: 'Your husband mentioned an unusual problem. He claimed that he was usually cold and chilly after having sex with you the first time; and then hot and sweaty after the second time. Do you have any idea about why?'

"Oh, that crazy old coot'' she replied.

"That's because the first time is usually in January, and the second time is in August."

I loved the Touching the World book review. It put the goo on me for a bit of travel. Brian Gerry and myself drove half way to Sicily over a few Jugs of Czech Beer on the stength of it. We could not finish the trip as we were full, even missed the last bus home, had to hail a taxi. Felt woozey for a few days after. Not as able for the long runs as I was. But the talk (biking) was good.


Have a good Christmas and new year!

Happy new year to you all and may it be a great year for biking,


A Very Happy Christmas and New Year to you all, from myself and the other Swindon Members.

Ian Bridge (Swindon Group Secretary)

Hello, I’m very interested in Jawas though haven’t owned one for near to 30 years. Having said that, I’m saving hard at the moment to buy a Jawa 350 Retro sometime late spring next year (2014).

My original bike was actually a CZ 250 bought second hand back in 1982. I’d been abroad for several months and wanted something cheap to get me around though was most certainly not thinking of a Cz or Jawa having previously owned jap stuff. Once I got used to the clunky gear change and relatively slow speed totally fell in love with it. I rode it mostly locally around Cornwall where I used to live but did do one long trip where I took the bike overseas. I rode from Cornwall up across the south of England to Harwich where I caught the ferry to Ostend, from there I rode through Belgium into Germany and 70k the other side of Frankfurt where I met up with a friend In the little town of Fulda. From there it was back into Frankfurt for a couple of days then onto Holland and Amsterdam. From Amsterdam I again caught the ferry back to the UK and on up to Yorkshire to stay with my then girlfriend. Finally it was back down to Cornwall. In all that the bike was amazing and a real pleasure to ride. The engine did misfire once in Holland when overtaking a couple of lorries but that was most probably a bit of dirty in the petrol as that was all it did.

To say I’m looking forwards to owning another Jawa is an understatement. I currently ride a Harley Sportster which suits me fine as I’m not a speed freak and usually cruise along at a steady 50/55 mph so the Jawa will suit me down to the ground. I still visit family and friends down in Cornwall so the plan is to ride the Jawa Retro (hopefully bought from F2 Motorcycles in Wisbeech) down to Cornwall and leave it there for when I’m visiting.

All the best, Pat Heffer

Letter Home

Dear Mom And Dad,

Our Scoutmaster told us to write to our parents in case you saw the flood on TV and are worried. We are okay. Only one of our tents and 2 sleeping bags got washed away. Luckily, none of us got drowned because we were all up on the mountain looking for Adam when it happened.

Oh yes, please call Adam's mother and tell her he is okay. He can't write because of the cast. I got to ride in one of the search and rescue jeeps. It was neat. We never would have found Adam in the dark if it hadn't been for the lightning.

Scoutmaster Keith got mad at Adam for going on a hike alone without telling anyone. Adam said he did tell him, but it was during the fire so he probably didn't hear him.

Did you know that if you put gas on a fire, the gas will blow up? The wet wood didn't burn, but one of the tents did and also some of our clothes. Mathew is going to look weird until his hair grows back.

We will be home on Saturday if Scoutmaster Keith gets the bus fixed. It wasn't his fault about the wreck. The brakes worked okay when we left. Scoutmaster Keith said that with a bus that old you have to expect something to break down; that's probably why he can't get insurance.

We think it's a neat bus. He doesn't care if we get it dirty, and If it's hot, sometimes he lets us ride on the fenders. It gets pretty hot with 45 people in a bus. He let us take turns riding in the trailer until the RCMP patrolman stopped and talked to us.

Scoutmaster Keith is a neat guy. Don't worry, he is a good driver. In fact, he is teaching Jessie how to drive on the mountain roads where there isn't any traffic. All we ever see up there are logging trucks.

This morning all of the guys were diving off the rocks and swimming out in the lake. Scoutmaster Keith wouldn't let me because I can't swim, and Adam was afraid he would sink because of his cast, so he let us take the canoe across the lake. It was great! You can still see some of the trees under the water from the flood.

Scoutmaster Keith isn't crabby like some scoutmasters. He didn't even get mad about there not being any life jackets. He has to spend a lot of time working on the bus so we are trying not to cause him any trouble.

Guess what? We have all passed our first aid merit badges. When Andrew dived into the lake and cut his arm, we got to see how a tourniquet works.

Steven and I threw up, but Scoutmaster Keith said it probably was just food poisoning from the leftover chicken. He said they got sick that way with food they ate in prison.

I'm so glad he got out and became our scoutmaster. He said he sure figured out how to get things done better while he was doing his time. By the way, what is a pedal-file? Do you use it on a bicycle?

I have to go now. We are going to town to mail our letters and buy some more beer. Don't worry about anything. We are fine.

Love, Your Son.

Dating in 1958!!!

You need to be able to remember the era to really enjoy this.

It was a hot Saturday evening in the summer of 1958 and Jack had a date with Peggy Sue. He arrived at her house and rang the bell.

"Oh, come on in!" Peggy Sue's mother said as she welcomed Fred in. "Have a seat in the living room. Would you like something to drink? Lemonade? Iced tea?"

"Iced tea, please," Fred said. Mom brought the iced tea. "So, what are you and Peggy planning to do tonight?" she asked. "Oh, probably catch a movie, and then maybe grab a bite to eat at the malt shop, maybe take a walk on the beach."


"Peggy likes to screw, you know," Mom informed him. "Uh...really?" Fred replied, with raised eyebrows. "Oh, yes!" the mother continued. "When she goes out with her friends, that's all they do!". "Is that so?" asked Fred, incredulous. "Yes," said the mother. "As a matter of fact, she'd screw all night if we let her!" "Well, thanks for the tip," Fred said as he began thinking about alternate plans for the evening.

A moment later, Peggy Sue came down the stairs looking pretty as a picture wearing a pink blouse and full circle skirt, and with her hair tied back in a bouncy ponytail. She greeted Fred. "Have fun, kids," the mother said as they left.

Half an hour later, a completely disheveled Peggy Sue burst into the house and slammed the front door behind her. "The Twist, Mom!" she angrily yelled at her mother. "The damned dance is called the Twist."

Boozing Bikers

belfast bottle

Belfast Ale 4.5% ABV

Christmas is a time for treats so the whole family went up to Belfast for a night. The kids were happy as we stayed in a hotel with a pool and gym, they also liked having a TV to watch from the Bed. Breda liked the shopping, Belfast still has a lot of variety which the many smaller shops provide. I was happy with a visit to the Crown for lunch. And look what I found.

Whitewater’s most popular brew this aromatic ale is brewed with the addition of Torrified wheat and roasted barley. Rich fruitiness is followed by a gentle hop flavour leading to its smooth succulent finish. Available in cask, keg and bottle.

beer drinking biker

I am not sure what Torrified Wheat does but Belfast is a clear dark amber ale with an off white head, some soft carmel and roasted malts followed by a hoppy after taste. That little bitter finish for that extra bite. There is just the right amount of hops to give this ale good flavour without overpowering the senses.

It is widely available in bottle form around Ireland. Price is usually around 2.99 euro.

Cheers, Mick.

Vintage Jawa beauties descend on Mangalore roads.

Mangalore, July 15, 2013: As part of 11th International Jawa Day, as many as 25 Jawa and Yezdi bikes participated in a rally in Mangalore under the aegis of the Mangalore Jawa-Yezdi Motorcycle Club. It was a pleasure to watch these vintage beauties. The event was flagged off from City Gate Complex, Kadri.

The rally which was a feast to watch concluded at its starting point, after passing through various prominent roads including Nanthur, Bejai, PVS, Navabharath Circle, Hampankatta, Kankanady and Bendorewell.

The Mangalore Jawa-Yezdi Motorcycle Club has been organizing this rally since 2007. The number of participants which was just three during the first year, rose over the years and now stands at 25.

Mangalore2 Mangalore1

This year JAWAday is Sunday, July 12. We have been doing this a long time and it is very popular in some countries. India and Bolivia go all out. We need to get more Europeans (Irish and UK people) out on the roads waving a JAWA fist at the world, in triumph! Thank you

One tank of fuel

honley hd1

A Huddersfield man has spent 18 hours riding a Chinese 125 at 30mph. Jason Lodge, 52, did the 520-mile journey from Huddersfield to John O’Groats on one tank of petrol, with enough left to pour a trickle into a pint glass. He says the Honley 125, which he sells from Earnshaws Motorcycles, did 173mpg and the journey cost £19.

The Question

Thank you all and a very happy new year to you all. Can you please help me with some information. The few 350s I see for sale and those that have been sold recently all seem to either have had major engine work done to them or are being sold with a truck load of spare engine parts. Is there a particular reason for this, are they prone to engine failure or does the two stroke engine wear twice as fast as a four stroke? I'm trying to make a good decision as to what bike to buy to add a sidecar to (or buy a combination) without landing myself with a lot of expensive work.

Best wishes to you all

David Wilson

The Answer

One or two things from my limited experience about JAWA sidecars:

a) They're not particularly prone to wearing out the engines. These motors are pretty tough. But the carburation needs to be set up right, and the ignition points -- if we're not talking about the modern machines with electronic ignition -- need to be looked after quite regularly. With electronic ignition, one might ignore that advice. Against all that, a two-stroke engine will in fact wear out that bit quicker than a four-stroke, all else being equal. That's mostly pistons and cylinders, though. But these days, the wear differences are not as pronounced as they were fifty years ago.

b) If it's a premix machine, run it on 30:1 rather than the factory-recommended 40:1. The modern machines with Mikuni oil pumps take care of all eventualities so long as the cable settings are set up as they should be.

c) If it could be managed, fit an O-ring drive chain in place of the original. They are available. From my experience, an O-ring chain is almost impervious to wear, particularly within a fully enclosed chaincase that's kept packed with grease. I hardly ever had to adjust my O-ring chain, even with the Velorex sidecar fitted.

d) He'll have a dependable cruising speed of 80 km/h, 50 mph. Maybe a little more on occasion, but as a regular diet that will be his lot. On anything other than motorways, that's as fast as he'd wish to go.

e) the swinging-arm bearings will need occasional dismantling and greasing. Do it regularly, and it's a simple half-hour job. Neglect it, and it's an all-day nightmare at best.

f) If he's in the UK, David Angel of F2 Motorcycles wouldn't steer him wrong (no pun). He knows his way around both JAWAs and sidecars.

Wear Your Club Shirt

Brennan jumper

Pat Brennan out-binged us all at the Christmas Party. When raiding his extensive wardrobe of tee shirts for the Christmas bash he recited an ancient Hebrew Chant, resurrecting the Jumper his sister Martina knitted for him many moons ago. The enchanted Jumper is surrounded by stories, rumors and mystery. It is claimed that as payment Martina was given the choice of any JAWA Club man she wanted to become her husband. But I can tell you Martina had that choice already. She got her looks from the other side of the Brennan family. It is also said that the jumper has never been washed for fear of what might be released, another claim is that if it got wet it might never dry, and Bray would tip into the sea with the weight of wet wool???

Yet more proof that choosing your bike will not only change your clothing but it can alter your whole life.

Do send in a photo of yourself in a club shirt and tell us a little about the occasion.


We are open to suggestions, for this years logo. Send us artwork or ideas to make the 2014 shirts better then ever.

It may be just my age but the months are just racing by. Let me start by hoping 2014 proves to be a healthy happy and successful year for you and yours. We have been fortunate in Ireland and enjoyed a mild winter, up till the December & January storms. That said there has not been much biking. Early morning ice and the short days are as good a reason not to venture far on two wheels as any. Now is a good time to do any preparation work needed to make sure you get the best out of the summer months.

Time also to start thinking about the JAWA Rally 2014. I am of the minds that if it is not broke don’t fix it. So I suggest that we enjoy the pleasures of Redcross again, at the end of April. I have not booked anything yet so let me know if you have any preference. I know April is early but with caravan accommodation as an option it is a nice start to the season and does not clash with any other events.

The American Register organizes JAWA DAY each year. Ita an opportunity to do a bit of biking, solo or with friends. If you do get out and about remember to send me a photo to me. There could be a prize. YouTube clips are also acceptable.

Material was a little light on the ground this month. I have taken a little license and turned some emails into articles where I felt others might be interested in the topic. As always thank you to everyone who contributed and please keep it coming.
