Percy and Tony arrived at Pyrenees Motorcycle Tours for a short break driving down from Caen which took them about 9 hours in the van which was mainly loaded with Tracy’s weekend essentials (Percy’s better half) and two bikes, one belonging to another friend Dennis and the soon to be infamous Yamaha TT600R just recently purchased off Ebay by Tony with the immortal words ‘shouldn’t need much to get it going’.
The symptoms of the poorly bike were these, very hard to start (kick start only) and often kicked back, would only run on tick over and cut out as soon as the revs picked up. Luckily we had a donor bike available and soon started to eliminate the obvious. One and a half days later, much swearing and scratching of heads the ‘three ace mechanics’ (Percy, Tony and Mr PMT) thought they had found the problem.
On comparing the flywheels, both should have been identical but the one from Tonys bike, we found out later, was taken off a TT600RE (electric start) which I’m sure all you anoraks will know uses a different CDI unit. The raised parts on the outer circumference of the flywheel that trigger the sensor are in the wrong place for the kick start models.
A replacement part was found the next evening, thanks to Ebay but unfortunately the only one we could find had to come from Australia where these bikes are quite popular. We were fairly convinced this would make the bike go as it should and in the video that follows you can see the result.
