Hi there guys.
The only problem with running premix is that when you shut the throttle at say 12500 rpm you are shutting of just about all your fuel which has your oil in it. Now if you are going in top gear at max rpm and shut down for a corner in that short preiod you are getting almost no "fresh" lube into your motor. It is minor though, you still have 2-stroke clinging to your motor parts. With your autolube(injection) the amount of oil being pumped is determined by throttle opening and engine speed. So if you are at max revs and shut the throttle the pump is still spinning a high speed like the motor and pumping more oil because of th increased engine rpm. Run premix with a very good/expensive oil.
