    Were do you ride

    you need to double check everything as this is a little low but your RPM`s were low stock unless it is VERY hot were you are

    after you double check everthing you need to take the 14/17R out and send it to Jerry with GOOD details and he will get it right I had to send 2 14/17R to him for tweaking now they are perfect

    Probably the prop is too agresive, put the stock prop back in a give it a try you were only reving 7900 to start you want to get to 8100

    Did you install metal SC washer with the stage 1 kit? If not get them out of there since people are see these go out really early.

    Jerry is the owner of this site. He owns the online store to the left on your screen <-------- He takes apart superchargers for $50-75 depending on what you're having done. Purchase metal washers and have him do the install.
