I just installed my Yosh pipe on my quad and it runs like a champ. My only question is I didn't notice any exhaust gaskets upon removing the stock pipe so I just put the yosh on and it "sounds" like there is a slight leak at the head but I can't feel or smell anything coming out to speak of. Any help?

 

do you mean where the header connect. i took mine off to and didn't see any

 

Yeah that's exactly what I mean. You didn't see any either? Wierd. Anyone else?

 

Guys,
You need to remove the copper crush gaskets with a small pick or screw driver. They are pressed into the exhaust port. Then buy new ones and put your header back on. You are losing a little power with that leak.

 

Look closely at the cylinder head where the pipe and head bolt together. The gaskets are there....it's a little hard to see them 'cause they are compressed.

 

I replaced the gaskets yesterday and it fixed the little leak and also it does run quite a bit better. Can't complain about that because it was running awesome before!
