There isn't much to see, just a header and slash cut beginning of a MAC pipe:

If the engine is the same basic idea as a KZ650 or older KZ1000 I'll bet I know what happened. The 4 headpipes have to slip in the exhaust cutouts on the head obviously to crush the copper rings to get a seal. What can happen is by using thicker copper or doubling up the copper rings, you can easily build up too much gasket and not get the pipes in the exhaust cutouts. Probably one or more pipes are off center and tightened against the head casting not crushing the copper rings. I'd recommend using one crush ring in stock size only.

Stunning bike!

1 bad a## machine!!!

Obviously on the left side of the motor 1/2 cylinder...

I would think with your hand in close proximity of the exhaust ports and with a twist of the throttle you should be able to feel the point of leakage... Yes/No?

Since you didn't mention any oil leaks of sorts, exhaust leak seems to be the culprit... Unfortunately with black painted cylinder/head and pipes, hard to say just where it is...

In using copper, one side is rounded and the other is flat sided. Rounded to the exhaust pipes, flat to the head.

Another neat little trick I learned from Plummen, Permatex copper gasket maker.... Just a light coat on the flat side to hold it in place in the head exhaust port. May find it seals the smallest of openings...

no,no,no,no.....you don't just get to show a a picture of a bike that cool and get away scot free......we are gonna be needing a complete history and some more photos if you expect to get any more replies.......that has a story to tell i bet and we'll be needing some info........peace craigsheik*yerbouti wrote:

My bike does the exact thing but on the right side. I never thought it was an exhaust leak but after inspection that makes total sense!! Thanks guys.
