So I've been watching alot of videos on how the team's tear down the race bikes and rebuild then I know to grease axles and and pivoting point but noticed they where putting grease on engine case bolts and the plastic bolts aswell ,is this basicallynthe same affect as putting anti-seize on bolts

I think it has to do with them rebuilding the motors so often. I blue loctite every engine bolt. No way would. I grease any of them.

They are mostly using titanium hardware, therefor they need to grease.

Okay yea I thought it had to do with the titanium hardware but wasn't sure , so fun when you get a new bike and tear it down and realize that the fa Tory doesn't grease anything lol

I could be wrong but i think it has to do with how evenly the torque is applied across the length of the bolt. Or how it makes them easier to remove and keeps the internal threads from getting marred up.

That is not grease, but rather anti-sieze. Dislike bolt material from tank inserts and engines requires this.

I use anti seize myself but I was watching a video of one of the guys from pro circuit a d he was using grease on all the clutxh cover bolts and alot of other bolts they even asked what he was doing and said he was using high temps grease on the bolts but didn't say for what reason

This is correct, it reduces the drag effect on the bolt which gives a more accurate torque spec.

This.
As PawPaw stated, the titanium bolts don't always play nicely with aluminum frames, steel threads or brass inserts. The anti-seize is to keep the threads from galling together.

Accurate torque readings are maybe a fringe benefit. cool

Braaapin' aint easy.

I’ve read previously that torque settings are based on dry threads. Greasing, then torquing, results in tighter bolts.

The last comment is very true, especially concerning some OE top triple clamps. On my Hondas and my current Kawi, if I grease the bolts, the top clamp will continue to compress till the gap is completely closed. Doesn't have this problem with the lower clamp, just the top. I'm a big believer in greasing/antiseazing bolts, but not on these. KTMs clamps don[t seem to be an issue

Some bolts on helicopters are torqued by measuring how far the bolt has stretched. EG tighten, measure, tighten, measure, until it is x thou longer. Eliminates thread drag inconsistencies.


Could be the secret the factory teams use on sprocket bolts....l
