you guys in the states are lucky, in the states I would run regular gas but in Canada they pump so much ethanol and other crap into our regular gas that premeum is the only thing that keeps our two-strokes alive. (besides I'm already paying double what you guys do for gas so whats a few more...

I finally got my old js440 out for a ride today (my first ride ever). This is the best thing I have ever tried in my life! I cant wait to get out to the lake, so far I just got to try it in the slew across the road but I think that little taste has sparked an infurno, I think I have finally...
