Cool you don't live that far away from me.

Anyway, your stock spur gear is 47 teeth and your pinion gear is 18, if you want more acceleration (with less top speed consequently) you would want to get a smaller clutch bell or bigger spur gear. I couldn't find any different sized spur gears so you would have to get a new clutch bell.

the less teeth the more acceleration
