Hiya, hope someone can help, with this problem.

If its revved to or past 7 thousand revs and shut off it back fires.

Has anyone got any idea what’s wrong and if anything needs to be done?

Hey buddy, I don't actually have a solution to your problem but I think it is best if you give the make and model of the bike? That way people should be able to help you more.

Welcome to the forum too
