Torque Specs

I know this is probably on this site somewhere but what are the torque specs for the exhaust pipe bolts on an 83 GS1100E ? Thanks.
 
Looked at the site and downloaded the manual. If the torque spec is there I couldn't find it. I'll continue looking. Anyone know?
 
Looking at page 86 (7-6) it doesn't have a torque value for the exhaust pipe plates, unless assumption is the torque value for the clamps and plates are the same. (6.5-10)

7-11 lb-ft on my GS700E. Probably not much different.

If going with stainless bolts, might put a good coat of anti-sieze on the threads. SST and aluminum are not dear friends.

Hopefully this might get you underway.


Not to be rude, but your opening statement, "I know this is probably on this site somewhere but," creates a mental block for many of the most knowledgable here. It says, you didn't search, or attempt to even look, why should they.

A better opening statement would have been, "I searched through 1000's of threads, and even found thet the manual on Bikecliff was not clear."

There is a ton of information on this site, and many very knowledgable people who will help one help themself.

Anyway, just pointing out the dynamics of the forum. I'm sure there are 100s of threads on the exact same topic for the exhaust bolts. Only thing is that they are not titled "83' GS1100 Exhaust Bolt Torque Spec", instead they are titled "Need Help," "Anyone Know," or any other wild title name that can be posted.

The forum is a library, but does not function as one would believe a library should.

Peace fellow GS'er.

Thanks for the info and not trying to be rude either or create any "mental blocks". I did look through the specs in a Haynes manual and will continue looking. The numbers you mention do sound reasonable. Anyone with a 1000 or 1100E that can provide input?
 
I'd say that torque spec looks reasonable. The sealing gaskets for the exhaust pipes are the crush type so you don't want a lot of torque on those bolts. I suggest you keep the mufffler hanger bracket loose while torquing the flange bolts since you don't want anything to bind up. After the flanges are tight, snug down the muffler bolts.
 
Ok I think I found it. In the manual under Standard Torque settings for a 6 mm flange bolt it says 7 to 10 foot pounds, like you said. I hope this flange and the exhaust pipe retainer mentioned in the part of the manual about reinstalling the exhaust are the same.
 
Yes, like Ed suggests, the gaskets are the crush type. Don't need a ton of torque. 9 foot pounds and call it the day.

Good tip on the hanger also. The faces of the tubes really need to be as parellell to the head ports as possible. Put the bolts in the hanger, but leave 'em loose, once the bolts at the head are at the correct torque then move to the hanger bolts.

You're right about leaving the muffler bolts loose when tightening the flange bolts. That is what it says in the manual about reinstalling the exhaust which is what I did.
