As I was smearing moly paste all over my . . . gears and splines (because I want my gears and splines to be REAL SLIPPY), I accidentally read part of the label. Normally I wouldn't do something as rash as reading a label of a product I'm depending upon to keep one of my motorcycles running well but it was . . . an accident. Anyway I believe (I can't swear to it at this point because, as I said, I accidentally glanced at the label in passing) that I saw that it was 65% molybdenum disulfide. It wasn't until later that I found myself questioning, "wait 65% . . . is that enough?" At what point is it moly paste vs. moly grease". This started me grazing on the old interweb looking for enlightenment. So far I've not found much. But I did find what's linked below. I haven't read it all yet but what I have read is interesting so I thought I'd share in case there are any other nut cases here like me that find useless information useful. BTW, if anyone can answer my question, "At what % of molybdenum disulfide does moly paste become moly grease.", I'd appreciate hearing it. https://apps.dtic.mil/dtic/tr/fulltext/u2/716940.pdf |

By Valvoline Product Support Manufacturer on March 5, 2019-Mike You are absolutely correct. Moly GREASE is 2% to 3%. I've seen it as high as 6%. Moly PASTE on the other hand is mostly Moly. The Moly which is similar to graphite, needs to be suspended in a carrier so it will stick. That's why you will not see 100% moly. |

My dad once brought home a can of 100% moly - it's a powder, almost black. It was purchased in this form so the company we worked for could mix it to custom specs. Not very useful un-mixed, and was messy like printer toner.

Now that all that moly stuff was cleared up, you’ll be shocked to know that most of us don’t use moly paste. The most common product is Bel Ray waterproof grease. A member (RATDOG) use to mix paste with Bel Ray and called it a schmooie. My last valk never saw any paste and I sold it with 155K and the original splines were perfect.

I have a rule, for the first service for a new (to me) bike I attempt to do it by the book. After that I might take poetic license. I figure every machine has its eccentricities and initially I might not know what they are so I play it safe. BTW, I mixed some of the Bel Ray in a couple places . . . just because. I can tell you one thing for sure, it'll be a while before I pull that damnable final drive out again. |

Only if you specify it your will,, and leave instructions as that stuff tends to get everywhere!

Sodbuster's pictures are good and I think they say what the manual says. Still... there's those people who use blue belray everywhere and have good "splines"... -Mike |

As it Is pouring right now I will Not go into the garage and look but I bought my moly paste from a supplier in Texas. Looks silvery gray when the lids off. Had in time for my first service and now at 140 G on the clock Still plenty left as long as I'm alive. And B T W splines still show mill marks. Yup-you'd be Hard pressed fer me to use Anything else on Phatt Ghurls splines. Seemed to me-memory  -it was good in excess of 200000 P S I pressure as it was used on drill rigs. RIDE SAFE. |

My feeling on the grease for the final drive is it HAS to be water resistant. If moly was used the splines have moly embedded in the metal. I never clean the splines with any solvent. Just a clean rag. Any heavy duty grease that’s stays put and stays greasy is going to protect the splines especially if they have been treated with a moly product. I use a tiny bit of moly paste and mostly heavy duty waterproof grease. See my slide show

I don't think you want too high a concentration of moly, in any case- years ago i read an article which said it was actually an abrasive in very high concentrations. It needs to be used sparingly with lots of grease.
FWIW.

They're looking at stuff to replace or augment silicone
in computer chips... they've made stuff about as small
as is possible with silicone. There a class of "2D"
materials like graphene that can be used and made
as thin as just a couple of atoms.
One such 2-D material that has shown promise because,
unlike graphene, it is a good semiconductor, is
molybdenum disulfide, he adds. It has already
been used to create flexible electronics and a simple
microprocessor.
