Good advice

triple grip clutch. the stock one is really bad

IRP clutch is best drag elimator otherwise set up a new set of frictions with a little more stack to pressure plate air gap via other brand frictions. I used irp Carbon fiber frictions. Also oil viscosity try a few different maybe redline lightweight shock proof at only 200cc

At minute 35 I explain how I use a dremal cutoff wheel to carefully cut down the rounded edges

Primary I believe is either in transmission parts category page or crankshaft catalog. See my response to other comment I believe I listed p/n and provided link

The mod is to the primary gear, the Kickstart gear is usually ok but i think i cleaned it up as well. Your just looking for two clean square edges. The cleaner and more square edge you provide the better

@@jenningsbradley70 About both gears plus the kickstarter shaft in the problem one way

Anyone know if this kick start strip can get bad enough to prevent compression from building? Got a 2015 project sx with a shot cylinder and head. Replaced cylinder and piston and head with new OEM. Can’t get above about 90psi. Disassembled and reassembled a couple times because you can with the correct kick pattern get what feels like a decent kick but I’ve noticed as that pressure builds up while kicking it becomes extremely difficult to get an engaged kick(stripping increases). Would love to act on more than a hunch on this as I’m not super experienced and there is probably a world where I have something in the top end assy not right. Thanks!

THESE should be the parts you need if experiencing a skipping Kickstart, or a broken spring. I used RMatv to quote it PRIMARY DRIVE 33TPart #131307007121Mfg. #45232023033 KICKSTARTER SPRINGPart #131307004116Mfg. #45233054000 RATCHET GEARPart #131307005795Mfg. #45233052116
