Re: Top Speed, 80cc Chinese motor? what is the record?
Myself I mix my Opti2 as directed in my 5 gallon jug and then i put 4 cap fulls of Maxima 927 Castor in the mix just for a little extra prtection from the Castor oil.
Since I been running Opti2 straight up @ 100:1 or with the tad bit of the Maxima 927, I have had no oil related failures.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
