Not an Exhaust leak

Postby Gbrown4024 » Fri Aug 17, 2012 6:54 am



So I thought I had an exhaust leak, took apart a few things to get to the head pipe and found that it was not leaking. The noise was coming from above the head. As I inspected closer I found that what I believe is a manifold pipe of some kind (1st image) has a small 1/8 inch hole in it (2nd image). The pipe is on the back end of the right head just under a tab on the intake, it is chrome. It comes off the head and goes in behind the intake towards the front of the head then attaches to a rubber hose. Is this part of an EGR or PCV system? Given the mileage on this bike I am not going to pay someone to replace it so I am going to try and put a piece of rubber tubing that can take the heat over it and clamp it in place.

I'd have to research a bit,but the bike does have a EGR system and it really needs to be working.Patch it as best as you can.Just try not to pinch the hose shut.
Here's the best info I can find.

I believe that is it, in the picture the large circle contains a gray colored pipe, that is it and it is metal so I should be able to put a high heat piece of rubber tubing over it and clamp it in place with light pressure. Thanks!

That pipe comes from the reed air system. It injects air into the exhaust to stop backfiring when decelerating, with a hole in the pipe it will let exhaust backup into the pipe.you should be able to patch it with a silicone hose with no problem.

The repair is done ! I could not use a hose as I wanted to, long story. I did however have some spent 9mm shells laying around so I cut the end off one, split it length wise and coated the inside of it with JB weld. Snapped it on over the tube by reaching through the intake, close it up with needle nose plyers and then coated it with more JB weld, pic 1, then added a hose clamp for good measure, pic 2. Thanks for all the diagrams and input.
