Pipe Gasket?

(1/2) > >>

FastKX500:
Okay I took my pro circuit platnium pipe off so i could get it renickelplated..but i ended up painting it with heat paint, and i put it back on the other day but i dont remember taking a gasket off with the pipe? and i put all the springs on and the bolts and tightened them up but exhaust leaks where the pipe goes into the engine..not a whole lot but u can see it when i rev it up, anyone know where i can get a gasket for it, or if there isnt one in the first place? Im not losing any power..i just dont know if its good for the engine. Thanks guys

Usually there is a gasket for the exhaust pipe. You should have the 2 o-rings for the outside of the exhaust pipe (fits in the grooves) and then a thin metal gasket I believe. I usually put a thin coat of High-temp RTV where the exhaust pipe meets the engine on my 250 to prevent spooge leakage...oh that sounds bad...  :wink:

Anyway, I'm sure other more bonafide mechanics out there can tell you if its bad not to have it or if it really doesn't make too much of a difference. If you are leaking, you may be running a tad rich and need to check your jetting.

Am I right guys or am I a goofball & have no clue? :roll:

Actually you are loosing a little power. The scavenging capabilities of the pipe are being affected by the "leak" at the head, clean it up real good and apply that layer of hi-temp RTV and you'll not only stop the spooging (god that sounds bad :lol:) but you'll also pick up some lowerend grunt.

FastKX500:
So just put some RTV around the gasket?

Yep, clean the flange up and put yourself a nice bead between the o-rings. When the pipe get slid on it'll move that stuff where it needs to go. just let it cure over night aleast so the temp doesn't affect it.
