I notice my GS had a funny tick so from my background in mechanics I suspected an exhaust leak. Now keep in mind this bike had 1904 miles on it when I bought it. I checked everything from the tail pipe tip to the engine and discovered the exhaust pipes were loose where they connect to the heads. I tightened all the bolts but on one side the colar or flang is still obviously loose. I am suspicious there's no donut. There is no soot and I can't feel anything coming from the pipe when the bike is running. You guys or gals have any thoughts on this? Where can I get the donuts from and what's the part number and manufacture? Thanks.
I think you mean "exhaust gasket"?
GASKET,EXHAUSTP 14181-01D00
You're right. I took the flange off and saw the gasket so I added a washer to each bolt to take out the slack. It seems to have tightened the flange down. I still here the tick but I think it's valve tick. Any idea what the torque spec is for the exhaust bolts? I just put them on till it was real snug. Problem with that is my version of snug is most peoples, "oh my god not so tight".
Torque is in the book.
Real snug is OK by me.
Re-torque them after every couple rides as the gaskets compress down. Once they stay snug, check them when you do oil change or other maintenance.
Always use anti-seize on the bolts.
If the bolts don't go in far enough, they are:
1. cross THREADED
2. CROSS threaded
3. Possibly 1 or 2
If you poke something into the bolt hole, it goes way back into the head. Quite deep.
It is easy to cross thread the bolts. They go in at an angle, which is flat and true to the head. That is, they are not horizontal with the floor. If you remove the exhaust, you can check the bolts, threads and how far in they can go.
I have had heads with bolts that always wanted to go in crooked. Took exhaust off and CAREFULLY made sure they would go in straight. After that, I had to be careful on those pesky bolts to be sure they didn't try to go crooked again.
I ended up adding a washer to take up the space. The bolts would go in but the exhaust flang just wouldn't tighten up. Adding the washer did the trick. I tightened the bolts road it to warm it up and retightened them.
What book were you referring to? I need to get a book on this bike. Working on it would sure be easier with some sort of direction.
Thanks for the help.
