Looking for recommendations for high-temp anti-seize grease.

Specific application is ignition advance flyweights on older HD engines. The flyweights are a weak point, the pivot pins and the pins in the limiter holes tend to gall, wobbling out the holes, overheating and stressing the springs which tend to break soon thereafter with bad consequences for everything including the rider's right knee.

After innumerable repetitions of inferior-quality Taiwanese aftermarket units, I just installed ostensibly high-quality Made In USA stainless steel units and better springs, manufacturer recommends high-temp lubricant with anti-seize. For the initial install I used a decent quality NGLI 2 and a little bit of anti-seize paste. Guessing, obviously.

Temperature at that part of the engine (overall) is unlikely to even see 300 degrees, put the localized temp on the pins could be a lot higher. The red dust from galling (aka "heat rust") is a very common occurrence.

Manufacturer recommends lube of pins at 2,500 mile intervals. If there is any way to extend this it's worth a lot because the points cam is held in by a surprisingly slight bolt that does not withstand repeated tightening and loosening real well, and it threads into the camshaft.

Any thoughts?
 
This isn't written in stone anywhere, but if the application is steel on steel, the general order of temperature resistance in the various anti seize metallic impregnated greases are from low to high:

1.) Zinc.

2.) Aluminum.

Check out Schaeffer #260 Perma Moly EP grease.

Perma MolyEP is a versatile, multipurpose extreme pressure, anti-wear, bentone base
high temperature grease that is specially formulated for use in the lubrication of
industrial bearings and machinery operating under heavy loads and exposed to high
temperatures.

It can lubricate the bearings effectively up to temperatures of 500-600°F

I was under the impression that nickle anti seize was to be used with stainless fasteners. I read that somewhere but no citations, unfortunately.

In regards to your question about intervals, you are probably going to have to test and find your own answers. Maybe put some anti sieze on that small bolt you speak of just to lube the threads and reduce wear.
 
You asked for high temp anti seize grease.. plus you mentioned rust..

-Dampens natural vibrating frequencies

-Treated with the latest, rust, oxidation and anti-wear additives

-Fortified with high concentration, high temperature, ceramic solids

-Stays in place, protects at extreme temperatures (-54F - over 3000F)

-Chemical and corrosion resistant

-Will not wash away

cci- no experience with harley here. however, old tractors use a similar setup. ive seen the rust, broken springs, etc. my solution- trc 880 aerosol. im guessing theyre supposed to be taken apart and cleaned and lubed regularly. with the tractors, this does NOT happen. so they get rinsed with starting fluid dried and spray grease whenever i see them. sometimes its a couple years before i see them again. so far so good.
