You have to becareful when using oils in a wet clutch bike. Go and ask ANY bike shop.
If your bike has a seprate oil for the motor and trans, (ala Harley, Indian, Royal Enfield) you can use a lot more oils (but, they all recommend desiel oils to take the pressure). But you gotta use corrct oil in the clutch area.
Now, you can use ATF for the clutches, (auto trans have clutch packs same as motorcycles) but ATF won't hold up in my motor part for long, but it will clean up an engine great, ATF has a lot of detergent in it).
A LOT of auto oils have additives to make them slippery-ier, (is that a word? Did I just make it up? Can I get rich when people use it??)
This additives can and will get into your clutch fibers make it'll make them slip, slip, burn and generaly make it a nasty day for you. Once in there the fibers are done for good. (From expierence I can tell you that).
Don't let anyone tell you different, just ask a oil saleman or look on a oil web site.
Many Die-sell oils don't contain these additives, (cuz of the extra heat these motors produce), hense why you can use them, but they do contain additives that are not good for your fiber clutches. I've seem what they look like after auto and desiel truck oils have been used, not good.
After 50 years of riding motorcycle and fixing 4 wheel coffins, trucks, and bikes, my advice, (take it for what it's worth), use oil recommended for motorcycles, 4 wheel oil for 4 wheels.
This is an expensive motorcyle, spend the extra $4 on the 2 1/2 qts for the correct oil.
The bike companies don't want you to use motorcycle cuz they have stock in the motorcycle oil companies, it cuz they are designed for motorcycles.
Would you take the advice from a guy who said it was cool to jump off a roof into a pile of bushes?
