I can relate to worrying , just make sure it's full of oil ! Oil is so much of a personal preference and could be debated
from every angle. I lean towards a motor oil for trail riding . ATF was discovered by low displacement MX bikes that
wanted minimal HP loss thru the transmission. Just my opinion after years of worrying , ha ha

Glad I found this thread. Thanks for the info, guys. I never had a 2 stroke before, and I got my KDX a few weeks ago. Although I haven't had much time to ride it, I have managed to squeeze in a 1 hour hare scramble, and a couple quick rides from the house. The PO said he was using a 15w40, and I was thinking about switching to an ATF before I do a 90 mile enduro on Sunday. Hopefully I'll get a chance to change the oil, and try it tomorrow afternoon.
Not just to confuse things as it's just MY personal preference ,, is a 10w60 motor oil.
Same 10 weight cold flow as recomended in manual but has much better viscosity when up to temperature.
IF you prefer a smoother vs. notchy shifting tranny , then this will work for you.
Total or Liqui-moly can be found at a decent price " yes, it's a synthetic " and oem in KTM bikes.

I just wanted to throw my $0.02 in, I recently switched to ATF type F from 10w40 four stroke oil and the trans feels much much better, way easier to get into neutral now.
