Permatex Ultra Slick Assembly Lube.....good? Ok for wet clutch? Experience or opinions?

I would think it should be OK. As I understand it, it's not a moly based lubricant and is similar to Royal Purple Max Tuff assembly lube. I know of several that have used it on a wet clutch engine with no issues.
 
Assembly lube should only be used very sparingly. Don't think it's needed at all when redoing a used engine as long as you make sure the top end is well oiled. And speaking of that, if you are redoing your '82 750, make sure you shim the oil pressure relief spring to increase oil pressure. Those engines are know to have problems with oil getting to the top end and crank.
 
Im with Ed.....manuals generally say just to oil everything while assembling. Ive never had any issues with just this. Some straight 30 WT on bearing surfaces, cam bearings, wrist pins...you get the idea.

Dry crank it a few times before firing. In other words, pull the plugs and roll the engine over with the starter. This keeps the RPMs minimal and allows the oil pumps to push oil thru everything first. Then fire it up.
 
Thanks for the info guys. Yes I am rebuilding my 82. Doing it slowly and wanted something that would not "run off' while I took my time. Most certainly have oil relief valve on my list!
 
I've used it with no problems

A little dab on wrist pins, cam buckets, etc help lube things up before you crank it up for the first time

I've had that little bottle for 2 decades
 
Ya, the best use for assembly lube is when you don't plan on starting her anytime soon or your assembly process will take a long time. Oil will run off over time where assembly lube wont. Just use it sparingly. A little dab will do you.
 
Exactly what I wanted to hear. Almost ready to put case back together. Then paint and hone jugs. Just painted upper case last week.
 
This is where I am at on the top half...

I have strayed from the original topic of permatex......




Been cleaning the bottom half of the case and decided to modify oil pressure relief valve.







Now time to shim the spring. Picked these up at the hardware store...



Now assemble and re-install....


 
Been making some progress lately. Got the crank in and case put back together. Thankful for a wife that let's me do this in the house :D. Been too cold out in the garage as of late!





 
When done toss a pressure gauge on it and let us know what pressures you are getting. My '80 750 gets about 40# at idle and the relief valve pops at 70#.

Is your 750 a four valve? I didn't know the two valve engines had pressure that high.
 
Its looking good, I will be very interested as you continue to rebuild. I am getting ready to start rebuilding the top end of mine. I took a long break, removing old gasket and cold garage demotivated me.

I've used this stuff on several motorcycle engine and top-end builds with no clutch issues at all.

I like it because it's thick and sticky, and the bright red color makes it easy to see if you've completely covered the parts. If it takes a few weeks before you're done, it's not going to run off the parts.

I don't believe it's moly-based -- it's a reddish, translucent fluid with no particles (no need to shake). Moly particles generally make fluids black and opaque, and require shaking (or a thick, pasty texture) to ensure the moly is evenly mixed.

That said, I'm sure it contains friction modifiers of some sort that could be a problem for wet clutches. But you need to use so little, it doesn't actually make any difference. You might use something like 1/8 ounce per engine if you're being overly generous.

Yes gasket removal is not fun! I got some of that gasket remover chemical....it was a total waste of money! It is finally warming up here and I have the jugs and clutch on at this point. This weekend I hope to have the head painted and installed. I did nothing to the head, but clean it, as the bike only had 7000 miles on it.....had a spun rod bearing as a result I believe of the design of the engine combined with an young, idiotic PO that did not change the oil and hot-rodded the bike.
