Attaching head manifolds.

[George S]

The exhaust seals that fit between the headers and the motor have a beveled edge. Which way should that edge face? It isn't mentioned in the service manual.


Cheers!

Which year and model of engine?

Exhaust seals?!??!

Must have got lucky at some point in life...

thanks for the reply speeddog... figured it out though. for the record it is a 2004 s4r. still having trouble though. after several attempts there is still a pretty good exhaust leak between the header and the pre-silencer. I have gone through two gaskets and this second time i even tried some of that copper gasket material. the bike was previously wrecked and the pipe that runs beneath the motor took a good hit... which could explain why the header was cracked as well. anyway, maybe the pipes don't fit quite right as a result of that. I'm considering welding those two pipes together. I would still be able to remove that section of exhaust to service the bike without any difficulty.

Still having exhaust issues with my '04 s4r
For the record, my bike was previously wrecked. The pipe that attaches to the header and runs beneath the bike, obviously took a good hit. There is a deep abrasion and it was slightly crushed. Possibly because of that, I cannot get a good seal between that pipe and the header... and I have tried multiple times. I was hoping that seal could be welded, but my friend says no. He says it will burn though the pipe. Any other suggestions for a good seal? JB Weld? An entire tube of copper gasket sealant? Anything?
