Massimo 500 secondary spring

Recommended Posts

Gonna be putting on an orange secondary clutch spring to try and help the underpower issue. Fun machine but is a turd when you need to spin the tires quick. Anyone else done any clutch work. Was also thinking about a new machined sheave later.

Got secondary spring on went for test ride. I'm guessing Primary wasn't all the way on the splined shaft and the nut worked itself off and ground the grooves away inside the sheave. Time to upgrade to a machined sheave from rhino

Yes, it is very important to have those splines in place before tightening the nut, this is the result. I have seen it on many yamahas as well.
