Gear oil for chain case?

I think we all had a consensus of finger tight then, "1 turn out". To be the sweet spot to not rub but not so tight to make the "wind" noise.

That's exactly what I did last year Dan. I think they want you to turn them 2 turns out. When I did that I said no way I'm running it that loose!

“Rub” on what? There is a roller and it’s spring loaded. The adjustment bolt acts as a limiter.
 
To answer the original poster we use Amsoil "Severe Gear" oil (which is an equivalent to brp synthetic chaincase oil) NOT amsoil chaincase oil.

I had a gut feeling that 1.5 turns out from a finger tight setting was much too loose, but whereas I broke it in by the book and maintained it myself by the book and was worried about warranty, I stayed with the 1.5 out per book.

If one follows the break in procedure and then the first chaincase inspection A(by the book), the sled has not seen much in chain stretching yet. Once broke in and lots of WOT short or long runs, the chain does stretch quickly.

I did have the dealer look at it while he had my sled, and yes 1 turn out should be the sweet spot.

The book should be updated to reflect that. Looks like I now have a stock looking color to my oil so I shall stay with what they installed until my next chain case inspection, then I will go back to the same type 75 - 90 Syn, I think.

Shall research the stock Yamaha chain case oil also. It looks impregnated through site glass, maybe graphite?
 
Any thoughts on why YAM wants such a large amount of turn-out? So many yrs of finger tight then 1/4 turn out its hard to do something different. lol
Correct me if I’m wrong but I don’t remember the Yamaha tensioners being spring loaded? My Sidewinders is spring loaded so backing it off 1.5 turns is necessary so it does its job properly.

You are correct about past and present tensioners. 1.5 is too much, any chain stretching and it shall rub.
 
I use to run ATF in my SRXs and Mach Zs back in the racing days. It's thin which is less resistance and if it's good for transmissions heck it should be good for a few gears and a chain.

In the winder I'm running Yamaha chaincase oil, not sure of the weight as the bottle doesn't indicate what it is.
 
75w-90

Yamaha, Yamalube now has a synthetic chain lube, ill be trying that.

Thanks for pointing that out.

On their web site it claims that this oil is called out in the Viper and Sidewinder manuals.

Hi Guys

So what constitutes finger tight as that is pretty broad
