I was going to post a seperate story but this posting has prompted me to reply now. I have a road going NSR and I purchased a lightened flywheel last year, I did not notice that much improvement as I road along. The biggest improvement was in my mind( I must be quicker 'cos I have a lightened flywheel) Over the last 3 months my bike has steadily got worse it is now at the point of only running on tickover. I sent my bike in to a specialist to try and resolve my probs, New HT leads and carb tuning + a strip down and rebuild did not cure my malady. It was suggested that my loom or TPS or PGM could be the culprit. I fitted new carbs with TPS no change, I fitted a new loom, no change, I tried a new air box, no change I tried a new PGM, still no change. I fitted new plugs...........wow the bike will now rev! I blipped the throttle to warm up the motor and BANG! something went wrong. On stripping things down I discovered the the flywheel outer face had parted company with the cam. I have a new standard unit on its was and hope to fit it this weekend. I am also hoping the this broken flywheel has been the root cause of my on going dilema. I have spent a considerable sum of money so far in elininating one prob after another. A big thank you must go out to Mr Nigel Moss for loaning me several components for me try fit and try before I went ahead and purchased them. Thank also to Andy for his help and support........I was soooooo near to jacking it all in and buying a 4stroke. So..... Dont use one unless yoy really have to.
