Ok looking for specific info on a few parts and there interchangeability..
Ok first carburetors what if anything is different between new gen to pre gen... Are they interchangeable ...
Second... Will a pre gen Cush drive and sprocket hub fit a new gen wheel... And what about the brake rotor...
Kinda noob questions but would appreciate the help

Search for the thread on this. I'm not 100% sure it is for pregen to newgen but there is one or more out there.

There were slight changes with the carbs between the newgen but they're pretty much all the same from what I understand. The cush drive and hub interchange. Haven't seen it first hand but it should.

As I recall, they are the same part between the previous generation and the '08-'12 (cush drive/sprocket/sprocket carrier). I'm pretty sure I clicked the "?" on the US parts diagram to confirm the cross reference between models but someone else can check again before they buy. ;)
