When changing my back tire and before I reinstall the wheel, I like to put lube / grease on the gear set. Normally use Honda Moly paste. But would this be okay:

Thank You in advance!

Conventional wisdom says yes, but I seem to remember that assembly lube doesn't last and is meant just for the first start up in an engine since first start up is dry and when the oil goes it just washes the assembly lube off. ( I could be wrong here) just double checking myself.
This Bel Ray assembly lube with moly is 1/3 of the price as the Honda.

Edit, As I was:
just answered my own question but will not delete to save someone else the trouble....
The Bel Ray Assembly lube is more of a grease. The Honda m-77 assembly paste is more of a paste and will stick to parts better.
The Bel Ray is between 30 - 40% Molybdenum disulfide . the Honda M-77 is 60% molybdenum disulfide. Honda recommends at least 60% on their gear sets and splines.
I miss the Honda Moly paste when it came in the larger tube! Now they changed the name shrunk the tube size to 3 times smaller but kept the same price!!!

And other moly paste out there with at least 60% moly just as good and cheaper?

Another edit: Check out this link and scroll down to where it says "spline lubricants." http://motorcycleinfo.calsci.com/Shaft.html

I would suggest you not use an assembly paste to lube the splines/drive gear. Assembly lubes are meant for that moment of start up w/o oil pressure and new components that are dry otherwise. They typically get flushed out with normal heat and oil pressure and are gone after the first oil change. No oil flow in the final drive, but plenty of heat. I suspect the assembly lube would go liquid and run where gravity and centrifugal force takes it.

Take a look at other Moly grease - one example - Sta-Lube SL3141 Moly-Graph Extreme Pressure Multi-Purpose Lithium Grease

Thank You! That is consistent with what I was taught about assembly grease! Sad part is: I asked the parts guy about that Bel Ray Moly Assembly grease as a sub for the Honda Moly Paste (because that is where I saw it) and he didn't know. But where I doubted myself is the Assembly grease had Moly in it. And I was taught long ago that moly helps the lube adhere to parts. So the moly being in the Bel Ray Assembly grease and what I was told long ago led to my confusion.

But.....I searched for the wrong terms earlier and found my answers and then some on the thread for "Rear drive maintenance."

Now....if I could get my hands on some Krytox teflon bearing grease for the shaft splines for a good dealio.....

I actually found a tube for my grease gun at Walmart. It's a high pressure Moly/Lithium grease in their house brand, SuperTech. Cheap, so I figured what the heck. It doesn't say how much moly, but when I use it I'll give it the finger test and see what it feels like. For the task, it's probably fine and bonus, I don't have to totally clean everything up and start using a different type of grease like my nasty red marine waterproof wheel bearing grease. (Love that for steering head bearings!)
