I believe that I just discovered that my 850 has a 750 clutch pressure plate! A couple of days ago, on a 140 mile run, I noticed a bit of slippage at WOT in 4th gear. Today I pulled the clutch assembly (which I have done several times for other reasons) and, for the first time actually measured the thickness of the steels, the friction discs and the pressure plate. The steels/friction discs measure correctly BUT, per Old Britts, (https://www.oldbritts.com/ob_clutch_info.html) the 850 pressure plate is supposed to be .102" thick; the 750 PP is supposed to be .225. The pressure plate in my bike is .225.
My measurement is taken at the edge of the pressure plate - where the splines are - not at the thicker center section. Do folks here agree that the PP in my clutch is incorrect for the 850?
