Random clutch slippage

[Kelster66]

Just finished the Columbia Liberator build and I'm experiencing random clutch slippage. It happens a couple of times for just a second and only on hard acceleration. Clutch seems to work fine otherwise. Any thoughts? This is a new motor with less than 10 miles on it.

Well for starters it's new, slight slip is common as the pads seat in, just open the clutch bay doors and give the flower nut a tightening by just a bit and that should fix it, maybe a quarter turn should do since it's only under high rpm is does it.

agree, I've seen some new pads so different in thickness that only three or four were grabbing initially - often just purposely slipping clutch at speed will wear down the high ones quickly

My clutch plate came with a thin coating of paint all over it.. presumably to prevent rust.
I'm sure that would have gone straight onto the pads and left a glaze that would need to burn off..
So I cleaned it off just the friction surface with carb cleaner, and gave the friction surface a good scratch with a file. No slips yet.
