I have been riding on this engine for a few months non stop now. this last tank fill up i ran out of gas in the middle of town and had to eyeball the mixture. well two days later i came to a red light. i pulled up to a hyabussa and decided to show him up. I carefully watched the opposing lite to turn yellow, so i could get a jump on him. the light went yellow. 3... 2... Wham go... I went no where. my engine went full rpm, my clutch was out and i was a sitting duck. needless to say the hyabussa burnt me. so i peddled all the way home. i get home remove my clutch case and find that the sprocket just fell right off. Some how i ate all the threads on the clutch shaft right up and there are like four very thing washers that were loose and the clutch case itself was eaten up. i think my chain was to tight for starters. but before i go and buy a new shaft, i need to know how to fix this right, and what made this all happen. In the beginning this bike was to save money on commuting. but now my girlfriend is calling it a money pit, cause i keep buying replacement parts. I don't want my journey with my motorbike to end. please help so i can continue racing and getting to work on time. thanks - Cory up in Mukilteo seattle area. oh and if anyone knows of a motorbike mechanic in the seattle area let me know.
