When adjusting the flower nut on the clutch, make sure that you now have the clutch lever pulled in and locked in place, the clutch pads and pressure plates will now be in the DISENGAGED position.
Remove the flowernut set screw and then tighten the flowernut until you can't turn the back wheel at all, from there, turn the flowernut counter clockwise a "notch" at a time until you get the wheel to turn freely by hand and stop right there and put the lock screw back in place at that notch where the wheel turns freely...If you forget to put the set screw back, your clutch will back off and start slipping
When you release the lever it should of course now have the clutch totally locked up in the totally ENGAGED position and at this point you should have all the slippage totally out of it.
