Thanks mucho piasspj - you're right. Googled that number and poped right up. Great price at Latus too - $5.63.

Whether your bike runs rich or lean is dependent on the fuel-to-air ratio going into the cylinders, not the amount of air being deflected over the outside surface. A richer mix does run cooler, but that doesn't mean an externally cooler engine runs richer. You're confusing cause and affect.
