If I were to change the sprocket setup to a 15/50 could I still run my tdub wide open without damaging the motor
15/50 sprockets, O-ring chain, D2Moto foot pegs
tweaked carb (127.5 jet, 0.019 needle shim, idle screw @2.25),
Rubbermaid "Action Packer" on homemade brackets
No problem running WOT, and srs is right about the oil and fuel consumption.
If your body weight is more than 200 pounds, you might not get any higher speed except on down hills
Since I've had Tdub my body weight has varied between 170 and 280 pounds. Small changes in sprocket ratio won't make any change in maximum speed with a stock engine. Though the TW has a nice, wide powerband, it simply does not make enough power to pull redline in most cases with stock sprockets. Changing the sprocket ratio a little simply changes engine rpm without changing the amount of torque the engine puts to the ground, so speed doesn't change.
