i havent done too much research into the setup, but last night i was looking at a thread on here and someone mentioned that they had heard too many horror stories to use a crank underdrive pulley. what all issues have any of yall had or heard? this was to be my next upgrade, but if it is going to be more trouble then it is worth i will look another route
