Title: exaust leak at cylinder port
Post by: J.Patterson on January 13, 2004, 03:14:43 PM: I pulled off the pipe and found deep grooves in the right side cylinder exaust port where the o-rings seat. Is this common? Any recomendations for a fix.

The grooves are caused by the pipe moving around. Not only does the silicon restrict movement, it will also create a better seal than the o-rings and give you more bottome end throttle response.

I change about every 60 hours (When I ring/top-end).

Title: thanks for the info.....
Post by: J.Patterson on January 17, 2004, 01:06:04 PM: The pipe mounts are solid. The bike had been dumped on the left side and the pipe had been repaired. The bend at the port does not line up "just as it should". The copper crush washer is also toast. Good to find out about the black silicone. I thought it was spitting Bile at me outa spite. Darn thing has an attitude! As far as Paul jumping outa good planes, what can I say. It took 60+ jumps and a tree for me to figure it out. How I wish I had the K5 then. The Drop zones and pits on Bragg would be a blast to ride.
