    i have the 29 tooth front pulley. what will be the differences between a 65 tooth, 72 tooth and 76 tooth rear pulley on drivability?

    What are you trying to achieve? I was thinking about swapping mine for better freeway performance.

    As a reference, the 65 tooth rear pully will give you overall higher gearing for better freeway performance - it will run at a relatively faster speed (MPH) in each gear at a given engine RPM - higher top speed performance, and potentially better highway gas mileage.

    On the other hand, the 76 tooth rear pully will give you overall lower gearing - it will have more low end torque and get off the line quicker - it will run at a relatively slower speed (MPH) in each gear at a given engine RPM. It will get lower highway gas mileage as in top gear the engine will be running at a higher RPM to achieve a given speed.

    Is a new belt needed to run the 65 tooth option?

    you think it would be a safe bet to go with the 72 tooth?
