I don't know about the maxima - but I like mobil-1 synthetic run at 36:1.
It runs very clean and I have never fouled a plug with it.

p.s. If you do want the bike to run more cleanly - consider having the
RB-Designs head mod done. The squish band is typically set up very loose on the bike - it runs much better after it is dialed in and the compression ratio is dialed in. A friend pinged me about a minor jetting issue recently - and I suggested he do this first.
