Thanks for the info. I can't check this forum at work. Something in the address here sets off our filter. Our filter calls it 'chat' and it gets blocked. Other bike (Street) sites don't get blocked :(
It's definately an exhaust leak. The FMF was new, I hadn't realized I needed the old rings off the old pipe! Oops, my bad, I warned you it was a stupid question! But I did have a small leak with the stock exhaust. I have a little spray spooge on the back side of the front fender since putting on the FMF. But more than that it SOUNDS like an exhaust leak. Same ticking noise as cars and streetbikes.
The FMF bolted right up on my bike no problems and wow what a difference. Completely different motor :) I did change the jets/needle with that, the carb was very clean. I'm running the stock SA, any simple ways to clean it out other than the drain screw? I want it as quiet as possible, I'll sacrifice the few pounds.
I picked up new o-rings at lunch today, the stock ones have seen better days. They didn't have the copper gasket in stock, so I'm gonna see how it does with just new o-rings. The stock copper gasket was fairly dented, it was consistent in the dent around the gasket.
Maybe give it good tap and make sure it is all the way in there too.
thanks again
