Exhaust pipe to engine question

I removed my exhaust to get to my broken starter. Now, I'm putting it back together and need to know if I need lock tite on the nuts holding the pipes to the head. There are lock washers already there and I was wondering about the high heat. Also I was wondering how much should I be tightening the nuts down? It looks like I could over-tighten them pretty easily. The last thing I want to do is break a stud. Considering one is already been replaced with a bolt.

I have never used locktite on the exhaust flanges (wouldn't the heat render locktite useless anyway?) If it has a bolt instead of a stud...you are asking for trouble. Get a stud back in it. I just use a small 1/4" drive ratchet with extensions to tighten the nuts, if you don't have a good feel for how tight you should get them, use a small torque wrench.:up:

X3 Just check them after you ride it a bit, the flange might settle into the gasket a little more, and the nuts might be loose.

I use some anti-seize on the threads. This keeps the nut from rusting and also prevents the stud from coming out when you pull the exhaust the next time you have to.

I use to have one of the studs coming out all the time... I used red (high temp) Loctite on the stud (head end) and it did not move again.

Then for the nuts, I use a double nut on each stud and they do not come lose anymore.

Make sure you get new exhaust gaskets. Torque the nuts to 20-30 inlbs. Then torque them to 60-80 inlbs. Do not over torque.

I also use a double nut on mine and the second one is a chrome acorn nut, dresses it up a bit.

Absolutely right thing to do, and yes the heat will defeat the lock-tite. Anything above 350 degrees will cause lock-tite to soften.

Get that bolt out of there -- You can easily get the proper studs at Ace Hardware!
That's where I got my last set for my other Evo engine bike.

:agree:

+3 or 4 etc. no locktite , no over tighten, use anti seize,new lock washer, recheck after couple of rides, . If stud backs out all the time replace both with new not a a big deal.
