Hey I have had a Coleman ct200u for about 4 months. The engine is a stock hisun 196 that’s ten years old and still has governor in it. Today I did some top speed runs, and after going till the governor engaged probably 8 times I was noticing the idle was way less rpm. Before this the bike shook so bad it could not sit on the kick stand while the engine ran or it would wobble off the kick stand, and now the shaking is gone. I checked the bike about 4 hours later and the slower idle speed and no shaking now seems permanent. Is this normal or is there something wrong with the engine?

Thank you
