Hey guys, my brother just bought a grass drag machine, 88 Qracer. Its sprocketed mighty huge in the back, about the size of a Dinner Plate. Anyone have a "Vitos" 305 kit on a Qracer, If so, what are you running for sprockets on it? Thanks. (By the way, this thing Rips like you wouldnt believe!)

 

When you say "Vitos", you talking about Vitos out of Michigan that specializes in Yamahas? Only big bores I know about are Trinity and LRD.

 

The size of the sprocket you want depends entirely on what you are planning to do with the machine. For instance, if you plan to do allot of paved backroad throttle pinning, a big rear sprocket resulting in a top speed of 38.5 mph top speed may not be all that exhilarating.
