Hi guys,
I've been thinking of running an '80 420 this year. I've been running a mix of Golden spectro/gas at 42 to 1 in my other Pentons with no problems. Any suggestions? Mike L, what do you run in your's?
I run Maxama Super M in all my bikes at about 32-35 to one.
My owner's manual says 50:1 !!!!! I mixed 927 at 40:1 with unleaded premium and it runs fine.
