How to put exhaust on the bike?

[Guest]

Well after doing a poor job putting the exhaust back on last time - because I didn't have new crush gaskets - I am trying to do it right this time. Any advice?

Is it OK to put the two small/middle pipes on the head first and then bring in each side pipe?

Also a couple of the bolts are shorter than the others. Hmmm. Maybe the fiche can tell me which is which.

I guess I could spray some carb cleaner on the head and try to get some of the gunk off first.

Thanks, guys.

Personally, I would hang the outer pipes (loosely), then add the center pipes.

Get everything to line up so it goes together, then start tightening from front to back.

Will do. Contemplating what to do with heat shield which has lost three of four mount points, and whether I should not put this together until I get this repaired or replaced. Hmmm

Yep - outer pipes first then the middle two - also helps to have about 6 hands...

Try brake cleaner as opposed to carb cleaner to remove the gunk - it leaves little residue compared to carb cleaner.

With bike on centerstand and cardboard underneath it, and muffler assembly bolted "loosely" together underneath bike, I used wire in the rear mount holes to raise up the rear, then I slid like a shoe box underneath the pipes under the engine to get it elevated and in the ballpark area, then moved the headers forward and up until I got those loosely seated and in place. When I got it all in place then I bolted the rear mounts, not too tight, and then started tightening the header bolts, but not too tight until I got everything in place. Once I got everything positioned correctly then I put the torque on all the bolts, evenly and sequentially until all was tight.

I would highly recommend anti-seize on all your bolts (appears you have some residue of it there).

I wouldn't worry about the gunk (it protects the finish ) at least until you get it all back together, then some spray degreaser and a brush.

I would consider anti sieze mandatory. Ive used it on all cycle exhausts Ive worked on and never had a problem with removal ,or loosening while in use. Careful not to use too much though. Ive had excess anti sieze get hot and drip on the pipe, leaving a stain.
