TONS of debate can be had on the topic, but as long as you are giving the crank and cylinder the lubrication it needs, go have fun!

Motul or the Maxima stuff will work fine. For road racing, I used 18:1. For part throttle, on-off the gas, no long sustained high rpms, you should be fine with something higher. Don't go crazy at 50:1. It's an old bike, it needs lube. Try 32:1 and jet for it.
