400ex or 450r thumb throttle, impossible for electric start, maybe adjust the valves might start easier when hot... hope this helps!!

When HOT use your hot start...it leans out the curcuit.

Do not give any fuel when kicking.

If that don`t get it, check those valves.

Good luck.


Also a auto de-compression cam may help too.
