Is it ok to use sae 30 weight oil with no detergent in the gearbox. I know some guys use atf is this a better alternative and if so do I have to flush out all of the previous oil before i put in the atf. let me know what you guys think.

Why do you want to run non detergent oil? That is for vacuum pumps and equipment that has filter elements that collect the carbon deposits that the detergent elements breakdown. ATF is good for a few tenths off of a drag bikes time over gear lube. I just wouldn't mix oils.

A few tenths??? Say WHAT??? You mean a few thousandths, if that....

 

I ran my FAST clutch the first year in a stocker motor on 80W gear saver, next year on 80W gear saver in my 4 mil cub, last year on ATF and this year on ATF, it lasted 3 and a half years....steels finally started to blue, so I figured it was due to retire, and I still keep it as a spare.

 

You're fine changing oils, ATF is cheaper and more readily available....you just have to change it more often.

 

I highly recommend a magnetic drain plug as well.
