    throttle cable install

    Alignment issue with chains

    Spend the time to get it right in 3axis. Had a motor that the base was off and needed shims. I've had to slot bolt holes also. Watch the chain as it goes on and comes off the drive sprocket. It should be fairly well centered.

    Clone heads

    The auto shop guy who has done valve jobs for me (before there was a stealth head) uses this on all his valve jobs. Car and Kart. It runs in his BridgePort Mill. One pass and all 3angles are done.

    Does Aero Matter on Dirt?

    You Make the Call

    Black flagged for rough driving ? I've seen people beat their way to the front with no black flag. Lead or 2nd Kart must have been high roller or the guy someone wanted to win.

    Clone piston rings low tension

    Synthetic oil doesn't break-in real well. It lubricates too well to let the ring and cylinder mate.

    Floor pans

    I made my floor pan out of a sheet of HDPE from Grainger. A fair amount of work but it turned out nice.

    Front End Adjustments

    Just to clarify raising and lowering. You want to raise the FRAME at the corner where you want more weight. This will require (on the Front) more washers on top and fewer on the bottom, so in effect you lower the spindle within in the knuckle, which in turn raises the frame. The LF will have...
