Airhead Exhaust Nuts - Copper or Regular Anti-Seize?

Frank06 · 04-01-2010, 03:46 PM

I've successfully loosened the exhaust nuts on my '81 R100RT using JT's neat wrench (immovable when cold, not bad at all when warm!) Does it matter which type of anti-seize to use?

thanks,
Frank

I used the non-copper stuff about six months ago and just took off my nuts (no jokes guys

) a few days ago to install new headers... the non-copper stuff clearly wasn't doing much and it did take a heafty puch to break free the nuts...

I say copper from here on in.

I just did this long overdue item on both my airheads today. I used hi-temp nickel anti-seize I had on hand from another project. It's a little expensive, but I figure it's cheap insurance, considering.

It's good to 2400F, probably overkill.

This bike sat for quite a while before I bought it. The PO would periodically start it, changed the oil annually but never really drove it much the past 5 years or so. I didn't know if the nuts had ever even been off. No way they would budge this winter when cold but I read where someone said after the bike ran they practically fell off. Thankfully mine were in this category.

I found this thread after posting my question; I think I'll use copper.

thanks folks

Felt like I hit the lottery this afternoon. On my recently aquired '81 R100RS I need to replace the pushrodtube seals. I asked the PO if he'd ever removed the exhaust nuts and he said no.

Little Kroil last night, blue tip wrench this afternoon, and off came the nuts, threads ok.

On my other bikes, I have a tube of Mopar Nickel antiseize that I've been using for years.

Don't have any long term stories but, when I put the exhaust nuts back on I used copper anti seize. Supposed to be good up to 1800 degrees. The head will melt before it gets that hot.

Definitely Nickel antisieze. I loosen mine and redo at the end of the season when she's tucked away for the winter.

The non-copper, non-nickel stuff I used (that didn't work) was rated to 1600 degrees... not to say the head went above 1600... just that it didn't work!

I've been using the copper stuff without problems.

I check the valves every oilchange, and I spin off the exhaust nuts everytime I pull the valve covers because I find it easier to get the little valve cover nuts started with the exhaust nuts out of the way.

I wirebrush the exhaust threads and apply fresh antiseize each time I do this.
