    Ultra 150 Expansion chamber to stinger gasket problem

    I can't seem to get this gasket installed because the dowel pins do not line up from the exhaust to the hole in the gasket. If I slip the dowel pins in the locating hole on the gasket, then the bolt holes don't line up. Am I missing something obvious? Click image for larger version.

    I have flipped this gasket every which way. The dowel hole is spaced on the same radius as the bolt holes on the gasket, but on the parts the dowel is on a wider radius than the bolts. WTF?

    Remove dowel pin, just make sure those holes are lined up or ski will over heat

    Meaning line up the slots that are half the length of the rest of them?

    Just use an Exacto to cut a hole. Use Permatex copper coat on both sides of the gasket, not silicon.
