Sometimes, as I'm going through the gears and I'm pushing the bike to go faster, the engine will rev up real high, but the bike doesn't go any faster. What gives?

Clutch is slipping.

Check to make sure you don't just have the cable adjusted too "tight".
A bit of freeplay in the lever is desirable.....

Makes sense. I have almost none. Didn't know it affect performance. Thanks, I'll adjust it tomorrow and let you know.

You might need to clean or replace the friction plates, either of which is an easy job. The clutch basket doesn't have to be removed. The minimum thickness of the friction plates is 3.1mm/0.12inch. "minimum" means none of the plate/friction material can be less than that thickness. Both sets of plates (driving & driven) must be flat. Cleaning the plates and sanding them lightly can help if they're above minimum thickness. Line up the clutch springs and lay a straight edge over them - they must all be the same height.

Also, try to use old fashioned dinosaur oil. Synthetic has been known to make these clutches slip.

Cleaning the friction plates: Use paraffin oil/kerosene/Diesel/distillate, etc. Be careful with solvents: the friction material is glued onto the plates. Probably not a good idea to use alcohol ketones like MEK or acetone.

Clutch is new. I adjusted it tonight and it made a huge difference. Thanks guys.
