Rear sprocket runout

[Yamifj1200]

"Pick the smallest rear you can....Seems like Yamaha forgot to add a 6th gear!  Do chanins really stretch?  Or do compopents suffer wear and hence chain loosens?


Yes cheap chains will stretch much more than you might think. They will also eat up both sprockets much quicker. Go with a new good quality chain and a 18 tooth counter shaft sprocket and a 39 rear tooth sprocket if you can. 18-40 will also work to lower your rpm's at cruise.

Eric is right for cruising but to save wear on the front tire try the 16. No promises on the fork seals though. Too much fun!!!!
