replace exhaust bolts with studs

[frozenfish66]

for those of you who have changed out your stock exhaust bolts for studs what size did you end up using? i searched the forum but never got a strait answer.

in particular I'm asking about a 81 750. i dont have the bike yet but it might be mine soon.

most of us swap studs for allen bolts. stainless usually. 8mm diameter and plenty of copper grease

[frozenfish66]

just goes round and round... i just don't want to wear out the threads on the head. plus it had 2 broken off bolts that ill have to take out. lol

I used 8mm studs with copper anti-sieze and copper plated nuts on my 81 750. Found the link in a thread here. They are actually for a BMW car I think. Also, NAPA sells a stud kit that works great, just be sure to get 8mm studs

you wont wear out the threads. how often do you plan on removing the exhaust? decent stainless bolts, not overtightened and lubricated will not damage the threads

[frozenfish66]

alright thanks for the info iv got some deciding to do

I've given up looking for the studs, hoping to find some stainless ones, I'm ready to settle for some polished 8mm stainless allens with lots of anti-sieze. The closest I got to finding studs was 8mm all thread you'd have to cut to length at ACE hardware.

I found thes M8 stud kits on NAPAs website I'm not sure what the difference is between them. I suspect the first one has a left hand thread at one end? which I dont think would work to replace a regular thread bolt so I think the second is the more likely.

NAPA sells a kit of 10 which are perfect. Comes with Nuts too. I've installed them on several GS bikes. Only 13 dollars

The links no worky -- all you get is some useless crap about needing a zip code. Man, what a punk web site. You'd never know Napa was a large nationwide chain.

Anyway, can someone please post up a Napa part number or application? You may be luckier where you live, but around here you're gonna just get a blank look if you ask for 8mm exhaust studs.

Its not great but its a million times better than Napa Canada which doesnt appear to have half the stuff of the US version and the website is so much harder to navigate.

I would'nt mind a part number too, Napa up here have so far proven useless. I am in Montana next week and wouldnt mind picking up a set for the future.

Thanks Tom

Those links work fine. Just click again on having the parts shipped to you. I did this mod a while ago and I am very glad I did. The thread size is M8 X 1.25. Mine are 43 mm long. I cut them from stainless threaded rod.

[SVSooke]

Here is stage one of my solution:

Going to cut the heads off then put them in using a couple of nuts locked to tighten them in.My 85 750 seems to need longer ones,these are 50mm.

I need to do this on my 1k. Like others have said, a Napa part number would be just Awesome!

[sschering]

How about a 45 or 50mm Stainless set screw?

$0.90 each
