Clutch works great
"This clutch grabs well and feels solid. only complaint it that the bolts flanged heads overhang the opening for the bearing cup in the center of the pressure plate. Bolts will need to be ground down or replaced with standard hex head bolts (grade 8. 8). I'm running with 4 heavy springs and 2 stock springs with a 143cc big bore kit and stock head. This spring combo has the clutch pull a bit on the firm side but makes for a satisfying launch. Running straight conventional oil so far, will switch to synthetic after the break in period is completed."
