Tusk Clutch Spring Set
Drew in GA
YZ85 HD Clutch Springs
They work great on my YZ85. The stock springs are to soft and makes smoking the clutch to easy. The tusk springs are a little bit longer and stiffer. You can feel the positive engagement!

Pro X Piston Kit
Geoffrey in OK
Works like a charm
Piston works as intended! Just make sure to look for the STAMPED arrow to point toward the exhaust port not the ink stamped marking!
