Ryan Young was ready to sell me a new braktec clutch mc for $180, supposedly it works with the stock hose. The clutch works ok right now so I figured i'd just look for a cheaper used replacement. But ya, gonna be kinda hard to find unless someone knows a specific year and model that works. Bah. 

Think the way is to take the banjo bolt out and measure,also measure the master cylinder bore

That works to figure out what size my clutch master is, but a lot of the used ones out there only give a year and make. Doesn't say what size bolt they use. 

Guys at Splatshop are very knowledgeable in the ways of the Sherco, might be able to shed some light on your parts conversion... 

Thanks Paul, i'll reach out to them.
