They will be Armstrong/Can Am/Bombardier MT500/MT350 ones, almost exactly the same cylinder head, so they fit perfectly. Just pop them in the head and bolt the exhaust stub in against them. I fitted them because my pipes were so loose in the head, I had a bad exhaust leak that caused really loud (and constant) backfires everytime I rolled off the throttle. And the leaking hot gasses were melting my front mudguard. A dab of silicone is helpful to hold them in place, or you could just use silicone instead of the gaskets. I used some to seal the exhaust into the stubs too. Only finished the bike off tonight and took it out for a quick spin and it didn't backfire once! |

mmmmmmmmmm they appear to be too small. the exhausts stubs wont slide inside of the gaskets, or are they supposed to be the same diameter as the stubs? |

Hi Craig, should be the same diameter as the stubs. I fitted gaskets as on my old MZ Rotax, outside diameter is 32mm, inner 27mm. Chris Edited by BK350, May 30 2013, 09:29 PM.
