    2010 fzs top speed problem after mods

    I have a 10 fzs that I recently did a riva cold air intake, ribbon delete, through hull exhaust, and r&d intake grate. At top speed I'm getting a sensation of bouncing off the Rev limiter like I ran out of power. Any suggestions why?

    Yes you are on the limiter the prop needs to be repitched for the mods you installed.

    You're hitting the soft rev limiter. Your ski is shutting down power to the #1 cylinder until RPMs drop back down below an acceptable range, then RPMs will come back up, and the cycle continues. You need a new prop or a re-pitch on your stock prop to prevent this and increase speed. I have very similar mods to you and have had great success with a skat 13/20. There are other options, but none that I have tried personally.

    BTW- if you throw a digital tach on your ski, you can literally watch the RPMs at wot go from 7800 --> 7400 --> 7800 --> 7400 etc on the soft limiter.
