    Drive train

    Something is slipping between the engine and wheels it revs higher than it accelerates I tightened the slipper clutch and replaced the clutch shoes and it still does it, could it be the clutch bell? I think the problem is after the 2 speed gears because occasionally it will shift to second at a low speed which would suggest the transmission is spinning faster than the wheels so the only thing I can think of is the diff , can they slip a little bit without totally disengaging or locking up?turning the wheels by hand the differential feels like it's fine

    Did you sand/clean the inside of the clutch bell and make sure not fluids/glazing was present?

    Agreed. Unless you broke a pin someplace down line or stripped a wheel hex. The differential does not have a clutch so it is direct drive to either or both wheels.

    Clutch shoes backwards? Maybe pull the trans apart and give the one way roller a little drip of 3 in 1 oil?

    Mine sometimes did this when the clutch got warm with the stock flywheel. It seems much better with the vented 40mm flywheel.

    i use a screw driver to scrap off gunk but i gently do this then i spray with brake clean and scrub with a wire brush, i also scrap off the spring when i remove the cb to help it stay clean.
