I've been thinking about upgrading the clutch and bell, and there aren't a lot of options with the 130mm clutch and bell that Kymco and SYM use in this engine, and what's out there is relatively expensive. Has anyone tried any of the 125mm clutches that are used in just about everything else with this engine or it's nearest relatives? Any feedback? Is there any reason you can't use one in the Yager?
