Commando 850 Cylinder Allen bolts install question

What say the experts ... recommended way for installing the four Allen bolts on an 850 cylinder? DRY, Blue Loctite, antisieze, or oil? Of course you can't re-torque them after running in, unless you remove cylinder head, a real PITA.

On a "related" note, I just replaced all the cylinder gaskets on my 1999 Buell Cyclone; cause they leaked oil :-( I used "Cometic" gaskets, using the "Hammer Performance method." (Buell and Sportster experts that I admire, see link below)



... i.e. lightly oil the four cylinder head bolts; and torque in sequence 9 ftlbs, then 14, then 22, then 35, and final 42 ftlbs. (for a Buell/Sportster)

I use ARP thread lube.

Good question........I think ARP lub is good ? on the same way , normally there are washers under the allen bolts heads , but some advised to avoid them thus more thread in ....I had seen some (Ludwig ?) putting some plugs ( teflon ?) on the top to avoid the gasket for crushing ??

I think I have posted this video link before



Having watched the video, I couldn’t fault their logic, so I bought a pot.

It’s expensive, but a pot will last a lifetime, and I think a good investment if it means no thread galling and accurate torque measurements.

Yeah you have posted that before... now I’m a convert too...!

Ok, I'm convinced too! Just bought a 10 oz. bottle off fleabay ... THANKS!

yeah thats worth having ready for any special fasteners.
