    @pelplouffe I know when you delete the side stand switch you need to loop it out, otherwise it'll have intermittent spark issues.

    Not saying that this is you problem here, just one to be mindful of.

    Doubtful, I don't have the specs but rings are cheap enough for either.

    @Mightyman Small, cracks or surface gaps that won't flex. it works pretty well. But absolutely not the long term fix solution.

    @britshgigolo It could just be well worn it's service limit.

    I'd take it to an engineering firm to have it examined, make sure it's within tolerance.

    I like 34:1 or 32:1 if your romping it, it's a shame the gear ratios are so short on a YZ. If you keep it fuelled on the over run, just a blip or 2, you can expect no issues, provided the engine has the correct fuelling mixture!

    These engines are awesome, and can withstand abuse, just got to keep it setup correctly.
