Re: Slipper clutch mod, oops?

Hi guys I am looking to do this mod to my 2018. - trying to do my research first. I am looking to get an increase over the stock clutch but nothing too crazy. do you recommend washer, ramp spring, washer set up? or should i go with ramp spring first, followed by two washers after?

any help would be great

thanks !

Re: Slipper clutch mod, oops?

this collar has to go inside the circular part of all 3 "Y" springs. It does not do it by itself, the 3 springs stacked up will fall onto the crankshaft. If you run this nut on there without lifting them and allowing this collar to go INSIDE those 3 springs, it will smash em flat. Bad.

the outermost part of the center hub nut is just like your counter shaft lock nut, you have to use a screwdriver or something to hit it into the recess on the end of the crankshaft, just like you peen the nut on the countershaft to lock it in place after you torqued it down.

while at it, measure stack height.. and if you do remove the center hub, be sure you instal it correctly. there is a wrong way it goes in.. and if the center hub is in wrong, those ramps (pictured above^^ ) won't ride up the oposing ramps of the clutch basket. It will just rock forward-backward but won't allow the clutch to SLIP

Then be sure ya offset the outer fiber, and line up the pressure plate as the manual shows.

negative .. LOL.
funny enough they were apparently on back-order recently .. Eddie Craft, a pro racer from up north, desperate to get some for a rebuild he had just done, called me and i sold him my spares. It took a couple weeks to get my spares replaced.

I run 2 full, and 1 with 12mm cut (that cut one goes on top) but I like a good deal of engine braking. I know a number of racers that run 2 fully cut, with only 1 full. Again, you can put the full one on the very bottom with 2 "washers" (remainder of cut springs) on top (little more engine braking) or reduce the spring tension by putting a washer under the full spring.. but ya gotta run all 3 pieces, cut or otherwise.
