im running the 13/40 combo right now and im getting smoked by 450s at LS on comp and spectator hills dont know if it is my gearing or what. On the trails i find myself in 3rd gear most of the time 1st is unusable as is 2nd gear 2 much rpms third gear is good when i keep the rpms up but most of the time it isnt as snappy as i would like it to be . im runing 20s on the dirt and in the sand im running 22s but i am going to be switching to 20s for the sand to keep everything the same. This is the gearing it had when i bought the bike it had 5 rides on it couldnt pass up the deal. you can see my mods below but was wondering if changing my gearing would help. i weigh 265 pounds.
