Hello everybody, I purchased (what I thought) was a 2002 yzf426. Bike has been amazing until recently my clutch began slipping then my cable snapped. I bought an EBC clutch kit and new cable and went to install it however my new clutch kit not only doesn't fit, but included 6 clutch springs where as my bike has 5. After checking the manual which showed an 02 having 6 clutch springs I checked a 400f manual and sure enough it has five. The odd part...vin # on frame decodes 02 yz 426f.....can't decode motor # but case says 399cm above header. Can anyone give me any feedback or help me decode my serial # on the motor?

Vin # - JYACJ01C12A027042

Engine # - H38E - 004925

Sounds like someone stuffed a 400 engine in a 426 frame...
