tranny oil

[SSTBANSHEE]

i was wondering why yamaha recommends 10w-30 4 stroke oil for the tranny instead of like a 80 or 85 weight 2 stroke tranny oil, is there any advantage to either of them? i have owned 4 strokers all my life and just bought my banshee last week, so im wondering....thanks

Good question.I was wondering the same thing.I was told that the honda 2 stroke stuff in the red bottle is great.So thats what i use.No troubles ever and also run it in my 2 kids Blasters.

advantage of motor oil is you can get it anywhere. dollar store, gas station, grocery store. lots of plates carry motor oil.

2 stroke gearbox oil as in the 80w or 90w type stuff, is pretty much only available through mail order or a motorcycle/atv shop. and its expensive as hell compared to motor oil.

 

pretty much you can use damn near anything you want so long as its not olive oil or brake fluid!

In most applications - it’s a trade off, dont forget about your clutch. I've seen guys try to run everything form ATF to Gear oil to Engine oil - the weight of the oil of these different types doesnt always mean they have the same viscoisty level. An 80 to 85 "gear oil" will have near the same viscosity index rating as a 30w engine oil.

 

I.E. It's tempting to use a light medium gear oil such as Amsoil MTF (at 9.6 cSt, but GL-4 protection), which would be great for power to the ground and gear protection - but NOT great for the wet clutch.

 

Amsoil MCF 10W-40 will work fine and is compatible with the clutch.

Those bouncing titties are hypnotizing.

yes they are. On a sidenote I have been told by many people and many other sites that type F ATF will work best for the banshee and it is cheap so you can change it evry third ride which is also good for parts.

i use to run the 10w40 atv oil because I have so many damn bikes in the shop and always changing oil so it is on hand. I switched to type F tranny oil and have never looked back. I split my case about 6 months ago and everything looked like new. I have no slipping on the clutches and those still look brand new after a year of hard dune riding. But everyone will have their .02 on what oils to run and mix with gas. So you can take it from anyone you want when your jar gets full.

Not true. It has to be a motor cycle "wet clutch" oil. The oil you run in your car has friction moddifiers and will cause the clutch to slip.

 

A quart of motorcycle oil and 2 stroke transmission oil are about the same price. Yamaha does it so they didnt have to come up with a 2 stroke transmission oil. It works and gets the job done but there are better alternatives out there.

So there I was.....having a few frosty adult beverages reading GrMeyer's post - I'm gonna give it a shot and run some ATF - (not cause you "said so" but because what you said ) got me thinking -

Two things

- 1st you have alot of 10w40....that made me think -we are the opposite here in my shop, I have alot of ATF type F.

- 2nd it makes sense - I run amsoil ATF type F in my 7 yearolds KTM SX tranny and change it every weekend after racing. Honestly we could probably go longer but I'm just wierd like that and do it out of habit not to mention the cost is low when on board as a snonsored rider. That bike has a wet clutch but sees much more abuse than a Banshee tranny will ever think of - from a little guy "bliping" the throttle as a rookie, to the motor running flat out at 14,000 RPM in dead summer heat w/ 100 degrees outside. The ATF holds up better than anything we have found.

 

Thanks for the backhand to the skull piece -GrMeyer - I'll let ya know how it comes out for me on this side.....

bingo......the thing you have to look out for is friction modifiers. people new to the banshee world will want the best oil and look tward high end "protection" but all you really want is high crush resistance and detergency, without high coushin which is wherethe protection in may modern oils are modified to hold a thicker film in the jounals and piston skirts. this, however, will prevent the clutch plates from making both complete and timely contact, neither will it dispell under pressure in order for the clutch to hold....

Just make sure you do a light run when your changing out the oils... That way you can get all the old type of oil out and go fresh with new oil after the drain of the mixed tranny fuild.
