I was chatting with some old timers that raced and they claim they run standard Tranmission oil in the crankcase, says it works great, works well with the clutch, low drag, just change it every few trips, has any one else used Plain old Tranny fluild?
(Chevy Grade)

 

My motor builder uses it.

Right now I am using Mobil 1 redcap.

 

Yeah I have heard of people using tranny fluid in there bike... I haven't heard of anyone having any problems..... But I don't use it.... I run Klotz flex drive..... Some times them old farts can be stuck in the past...

 

WE use good ol Castrol 30W in our blaster, we have used gear oil when we had nothing else up camping & it seemed to be fine!! It's thicker so thats maybe a good thing!
