15 tooth sprocket or 14?

the 15 tooth requires you to grind the case down, so the chain dosent hit, i would go with the 14

HA!! i knew i was right!!! another Blaster rookie keeps on learning!!! =))
 
i have 18s in the rear with 14/40 gearing and its great. i was riding 14/40 with stock tires but i didnt like it so i put the 13 back on. but now with my 18s the 14 is fine.
 
What should i get 15 tooth front sprocket or 14? My blaster is stock would appreciate your opinion.

If you have a stock motor and stock size tires,I would stay with the 13.if where you ride is small and you don't run much in top gear. I would try a 12.
 
I'm running a 15T front sprocket on 20" tires. I've never needed to shift to 6th gear but it also does not have a problem in tall grass either. Maybe the difference is power, maybe the difference is the ride height...
