Greetings:

Stock airbox should do well with 88-90. Try bigger first, jet down after break-in if the temps are too cool and power sub-maximal. 90+ for pod filter, bigger if you add a pipe. I ran 96 with the LeoVince, if I recall correctly. Be careful if you have to slow down suddenly after a long rip at WOT. Keep the throttle open a bit as you brake.
