Stopped by a yammy dealer and was recommended 10w-40 amsoil if I wanted to go to fully synthetic oil.... You guys think this is alright, or do I need an oil with lower viscosity?

The lower the W number the lower temp it functions properly at. 0W is rated to a lower temp than 5W so I would not go 10W if you have remotely cold temps where your at. Just go Yamalube brother. You have a $10,000 sled dont' skimp 20 bucks on the life blood of it.
Maybe off topic but what does the "slippery" oil have to do with the roller clutch assembly? So aftermarket additives such as Slick 50 are more "slippery" than the best synthetic? Just wondering because the Castrol Syntec advertises that it coats the engine parts with a super slick coating that actually bonds to the metal, dosen't seem to be any different than what the additives advertise.........Sherm
I feel ya bro I'm all about quality that's why I went with fully synthetic amsoil. But even on their website they only have 10w 30 and 40, I'm in Utah and I haven't seen it get below 0 here but I already put the oil in u think I should drain it and put something less viscous in it?
FWIW, I've been running 0w30 Mobil 1 full syn in my Impulse Nytro.
A few years ago, this seemed to be a popular choice among the masses...TY and SW.
I'm sure its turned into what 2s oil has become by now though..
Thanks for the discussion. Did some searching over on TY about this starter clutch issue. It turns out it is a miss-print in the service manual that is in reference to the R1 bike.On a sled there is no oil in the starter. On the bike the starter has a wet clutch. The type of oil is critical. My quad has the same thing in the transmission. I run 0-40 Amsoil in it . Amsoil states that this particular oil is okay for wet clutches. If the synthetic oil does not have the additive for wet clutches it will shine up the clutch discs too much and they will start to slip.
