Swindon Smoke Signals on the Subject of Small Engined JAWAs It was really interesting to see on the recent cover of Torque 4 2011 our National Club magazine editor John Woods very rare 1960 Jawetta which he had imported from the Czech Republic Now John with this machine he also hosts the excellent JAWA Moped web site wwv was the winner of the Most Original Machine at this year s International Classic Motorcycle Show which took place in April Compared with the hundreds of other Classic machines at this show this was indeed a great result for John and also for the Owners Club and showed that you didn t need a mega priced classic to win an award John s success with this machine took me back to my own adventure way back in 1993 when I took part along with 1500 other motorcyclists in the annual 500 mile ACU National Navigational Rally on the smallest capacity machine in the event a 50cc JAWA Jazz moped For those who might be interested I reproduce the report I wrote way back then of my trials and tribulations 1993 ACU BME CSMA National Navigational Rally This year s rally was to be held over the weekend of 3rd 4th July with the finish being at the East of England Show ground Peterborough For those of you unfamiliar with this event it basically operates as follows a There are some 55 checkpoints scattered around the country and within a set mileage you have to try and plot a route which enables you to v

Although this makes a very rigid but light structure for the frame the down side is that it makes working on the moped very difficult Normal service items plug points magneto clutch etc are fairly accessible but you need very thin hands and long fingers to be able to unscrew the down draught carburetor top or reach the throttle cable adjuster for instance The slow running screw and the main jet are accessible with a screwdriver through a small hole in the right hand side of the bodywork and the carb tickler is accessed by a finger through a similar hole in the other side of the frame The air cleaner sits inside an enclosed section above the engine and requires the carb to be removed first to be able to remove it The 3 liter fuel tank sits inside the front section of the frame and slides up from the bottom towards the steering head It is not possible to remove the tank without removing the engine first Removing the engine is a difficult job in itself since the rear suspension and the centre stand are both Wanderings International July 2011 9 fixed to the engine and have to be removed and replaced with it The rear wheel is not hard mounted as it might appear but there is a pivoting fork supported in bushes in an extension on the rear of the engine The bushes are lubricated automatically by the gearbox oil The upper end of the rear fork fastens to a single large spring located inside the frame under the seat The front suspension is by a

10. eers Joel 505 603 6513 jacob joel gmail com Wanderings International July 2011 1 Joel Over the years I ve done it 3 ways Sometimes I ve been successful squeezing the rings by hand while lowering the cylinder over them I ve also used hose clamps to compress the rings to slide the cylinder over them Seems to me I also used a standard ring compressor to push the piston into the cylinder from the top sliding it through far enough to slide the wrist pin in with the rings still inside the cylinder For the brake shoes try loosening off the axle bolt and re tighten it while holding the brake lever full on Then reset the shoes Bill English Joel Re Cylinder installation I doubt a ring compressor exists no conventional one that I have will work The cylinder has a chamfer on the bottom that will allow you to assemble without a compressor Check the end gap on your rings in the cylinder I don t have the spec offhand 2mm but it is likely in the book If not I d file the rings for 0 01 0 15 mm 004 006 Be careful as they are cast iron and brittle My procedure is to oil everything well and then slide the cylinder down to the top ring Use a small piece of wood ice cream bar stick to push the ring into the chamfer and eventually the groove as you apply downward pressure on the cylinder Work around the circumference with the stick Be sure the ring gap is centered on the dowel pin in the groove Keep going until all the
11. ers of machines from an East European country is surely unique So what s so special about the Club that has seen it survive through what has been a turbulent historical period and one of great change for motorcycling Firstly I believe it has been due to the dedication of a small number of members who even when times were bad soldiered on to keep the Club going The same applies to you guys in North America who are fortunate in having a few really dedicated people to Wanderings International July 2011 5 keep everything together for your group You have the added problem of covering a far bigger land area with fewer members but it is really important that you don t just be armchair members but do contribute and take part There is nothing more demoralizing than for events to be run and a magazine produced for there to be a lack of support Secondly of course it s the bikes themselves With basically what has been a minority marque in Britain the Owners Club has attracted owners due to the help advice and support it has been able to offer Thirdly there s been the support of like minded people and in many ways this has created the feeling of belonging to a very special select family Of course there are many other reasons why people initially decide to join but I m sure one of the reasons they stay is due to the good friendships that are made I very much doubt that the founding members of the UK Club way back in 1954 could ever ha

29. use the rings are pinned to keep them from rotating on the piston You can tell if the pins are in the ring gap because you can easily wiggle the clamp about a degree each way until the ring hits the pin If it does this then you are ready to drop the cylinder over the piston If the clamp does not move freely then a pin is not in the gap or the clamp is too tight Jim Downey Thank you All these suggestions are good and should work I know you all speak with experience I ll give it a fresh shot and let you know The piston rings are brand new and any damage to piston connecting rod or wrist pin is probably done by hammer already I ll know when it if it fires up I guess I ll keep you all posted after my move to the new place I wish I had asked before my adventures Joel Mike The JAWA Klub Prague 1961 in The Czech Republic is celebrating its 50th year We are trying to help raise some cash for the club by selling some special edition shirts patches and hoodies You can see them on the club page http www JAWAklub cz shop I will calculate the shipping and send you some prices if you or some members of the Register are interested in purchasing some items If you think that it is possible to put out the information on your page that would be great I thank you in advance Steve Clark JAWAsteve hotmail com Wanderings International July 2011 2 Mike I wanted to let the members of your club know that my hometown of Wilber Nebraska is having
