Im on a stock clutch and get a little "chirp" when shifting fast. It is not rpm dependant. It only happens when shifting fast. Never thought much of it, since the clutch grabs like a pissed off gorilla. Figured it was the nature of the clutch.
These are twin disc from the factory and I have found this clutch to be noisier than other single disc units from my past. Just keep track of "new" sounds once you get a few miles with it. From past experience, a squeak was indicative of a throw out bearing, but don't know for sure with these.
Re-watch my vid... Not sure if that's considered a squeak or a chirp but that's the Mantic kit including the new flywheel, slave/throw out bearing and pilot bushing. Apparently it's nothing to be concerned about, just annoying. It's been 2500 miles or so now including a handful of 1/4 mile passes and no issues.
