    Should i get a smaller sprocket (36-32 tooth) for my 4 stroke motorized bicycle kit since they tend to have a lower top speed than a 2 stroke and how much of a torque loss should i expect from going from a 44t to a 36-32t sprocket.

    It all depends on your transfer case....if you have the cheesy 3:1 transfer case i don't advise it if you touch anything not flat or downhill, plus the clutch slips at any speed under 18mph. I honestly don't advise doing anything under 15:1 total reduction for clutch longevity.

    Throw away the transfer case, all the mounting nuts and bolts. Get a 4g grubee and replace all the hardware with 8.8 stainless from the hardware store. Then hope nothing is wrong with the engine. If all is well should be good.

    Thats actually a very good price for just the motor, sprocket, tank and mounting plate.
