Did you make sure the woodruff key was in place between the crankshaft and the flywheel during re-assembly?

Check that the flywheel TDC mark coincides with the piston TDC...........
If they do not, your flywheel key is not in its place..............

Check your park brake switch, sounds like the rev limiter is engaging..........or just disconnect the wiring from the harness in the area oof the left headlight........black wire and a green and yellow wire going to the main harness, make sure you seal the main harness with silicone since water in the plug will turn it back on, or better still cut the green and yellow wire at the cdi...........

Yea man I have already done that only thing I can think of is maybe valves or you think reverse limiter. It started around half throttle and now it's doing it as soon as I touch it now

Does the reverse light work properly (when in reverse)?

Just to be sure it's not the PB limiter, cut the green/yellow wire up near the CDI... just in case the wire is chafed or pinched and shorting to frame somewhere.

Ok will do and keep you posted now you don't think valves could be at fault? Or that might make it hard to start too

Valve issues usually show themselves at start, yes.

I'm not thinking it is either m hoping it's something simple and not something inside the motor
