    Those are good numbers and I bet it's really hard to stay out of that throttle.

    You might have to order up a rack of rear tires for that monster! I know you're gonna be twistin' the throttle quite a bit. I am curious to know how many miles Zippers has seen out of this combo? Please keep us posted on how well it performs long term and its reliability. I would like to try out a 124 kit on my M8, but want to hear more feedback before I make a decision to go forward with it. Thanks.

    Based on what I've read, just about anything in the drivetrain can give you trouble past 130 ft-lbs of torque.

    Michael,

    Did Zippers delete your compensator and install a solid sprocket? Are you still running the drive belt or did you convert to chain drive?
