    It reduced my cavatation slighty. I still cavataion on the hole shot. You'll need different bolts, the OEM bolts are to long.

    rpms the same? Any changes in speed or accel? Do you recommend it or do you need more time with the cone?

    RPM's were the same. I'd hold off on it for now. I'll try to get some mph #'s for ya. All I know, yesterday I had another passanger and 3/4 of tank. I raced a rxp-x from a 30+mph roll and stretched him by half a football field away. RXP-x was bone stock. I wished I gps'd it yesterday. Ski felt amazing!

    Thanks I hope to start figuring out the nozzle rings next week. I am hoping to find a little more accel and a little more top end.

    Yeah I had similar results with the addition of my cone. The OEM bolts are to long and the gains are OK. Say you have three cavitation cycles on start, the cone reduced mine to 2 cycles. If your pickin up what im putting down. Blu, I'll be down at Ortley this upcoming weekend and I want to check out your ski and go over the gasket issues you had. Plus I want to see how your ski runs out of the hole and if I have more cavitation than you.

    If your having problems with hard or rough starting after a long ride, buy yourself a set of gaskets.

    low end loss

    did you or anyone feel any loss on bottom end (holeshot) i know the larger the cone the better the top end and the samller the better the bottom end, but was just wondering if the reduction in cavitation would outweigh the loss of space in pump and still yield a bottom end gain? whatcha' think?
