Re: Bearing ball stuck
What crassious said. If your engine is anywhere near new, your clutch needs adjustment anyway, so there lol. These kits engine has an awesome clutch system, it's just a little finicky. Once you get it dialed in, daily wheelies will blow a motor before wearing, let alone shredding, your clutch. Just don't lube it! Grease the gears, not the clutch. If you do accidentally grease any part of the clutch itself, brake cleaner, lots of it. Not only does it make your clutch slip immediately(duh) it degrades the pads (in my opinion/experience), making them prone to slippage forever.
I'm not 100% positive the above clutch degradation theory is correct, but it's what I've observed.
