    For Sale - Mikes XS carbs

    I got real nervous, I bought the mikes xs carbs before doing as much research as I could. I was being lazy and looking for an alternative to sticking with the stock carbs. The 650 guys seem to have had better luck after looking through their forum. However, I have to say, I ended up taking a...

    Need help with timing.

    Could be a bad coil on the right side. Not that I don't believe you but are you sure your carbs are clean? Is the arm for the points on that side loose? From experience here...its probably something you touched...lol

    Stripped spark plug hole

    Make sure the seat isn't cracked or missing a piece. If the plug won't seat, regardless of a heli coil, you'll be SOL. Use a little red loc-tite on the heli coil when you install it for some added strength. Just don't loc-tite the spark plug lol.
