This is my first post on this forum, I am usually in the Grizzly Forum. We have a 2000 Bearcat 250, and a ’98 Wolverine 350 (in addition to my 660 Grizzly). On both the 250 and 350, if we have to stop up against a rock or in a tough spot, so the machine is stopped, opening up either throttle just slips somewhere, the engines makes a low RPM, bogged down "Waaah", but cannot move the quad. A similar condition happens if we start at the bottom of the loading ramp with no "run at it". They both have correct wet clutch approved engine oil, correct clutch adjustment (one eighth turn back from felt resistance) and other than this dead stopped condition seem completely normal and run great. Tires are stock on both machines. It seems to be like a low stall speed torque converter problem: The clutch holds the engine speed down to where the engine is not developing much horse power, and yet will not break the machine loose. Worn/damaged/defective centrifugal clutches?

Any Ideas would be greatly appreciated.
