I use the Yamaha as thats what its made for. Maybe theirs a reason it doesn't say wet clutch on the bottle . So now it comes down to opinions 1. what Scootergptx or 2. old polaris tech said. Both know there stuff but have different opinions. When in doubt why go with the answer you want to hear.

 

The JASO MA-2 is all you need to see to know it's ok.

 

Relax, that oil is made for wet clutches. You are fine using it.

 

Thanks for all the feedback guys. Yall have been great throughout my whole learning process. I hope others who are as lost as I have been get a lot of useful info from all my posts.

 

Never seen a motorcycle that does not have a wet clutch, so your good with any motorcycle grade oil.

Another myth is synthetic oil can not be used for wet clutches. There are many full synthetic motorcycle grade oils out there.

 

Then you need to see and hear the racket a Ducati dry clutch makes..Never could get used to one..

 

Ducati, Victory, Harley and the many clones, BMW, Moto Guzzi...

 

If it has a foot shift and hand clutch it has to be a wet clutch. Not many CVT motorcycles out there.

 

Ahhhh I thought only automatic clutches were wet clutches. I am obviously new to all this stuff and not ashamed to admit it . I am glad all of yall guys have chimed in with great info.

I had bought this Castrol Oil because it was a steal from the Zone. I will be putting Yamalube in it next time though. Just to stick with the specialty brand or something like that lol.

 

That statement is not factual. Just because it's a motorcycle with a manual transmission, it does not necessarily have a wet clutch.

BMW, Ducati, many older Harleys, Ural, and the big Moto Guzzis have a foot shift and hand-operated clutch, as you say, but do indeed have DRY clutches... in the same way that cars with standard transmissions have dry clutches... outside of the sealed engine case and not bathed in oil. In these motorcycle engines, use of Energy Conserving oil will not affect the clutch, as it's never touched by oil...


BMW R80GS dry clutch. A small bit of oil can be seen at the bottom of the case, from a Rear Main Seal leak.

Wet clutches are those found on most other bikes and ATVs & dirt bikes, inside the engine case and bathed in the engine oil. As already stated, Energy Conserving oil should not be used in these engines because it's too slick, allowing the wet clutch (bathed in the oil) to slip.
