    Free airmods, Front hood spaced up, ecu cover removed, ducting from front storage to airbox intake, proper* reflash or scom, 250/60X riva ridplate, r&d intake grate, 2* wedge, low fuel - you may be getting close in cool weather.

    *one that removes speed limiter

    Good for nothing though really, a Yami will still walk you on smooth water, and in the rough it's likely to handle like shite.

    Maybe try 10.5-1 high comp Pistons, forged rods, custom tune, 16lb pulley, meth kit and e85 setup. I have no experience with this setup and don't know of anyone that does but I like the idea.

    You are going to be disappointed when you aren't able to get close to that speed in the heat.

    If I knew then (before I bought the 310) what I know now.....

    I would have bought a 2016 Yamaha FX SVHO. Tune only, 77 mph ski. Add simple bolt on mods, 82+. However, the trade offs are....

    Loss a lot of storage space. FX storage isn't as big in front
    Doesn't cut chop as well as the Kawi, but rides really comfy through it. Yamaha FX will unload easier in stock form, can be improved with bolt on mods.
    Hull isn't as strong on the FX. The Kawi hull is very strong. I call it a tank of a hull.

    So, if you are always trying to be top dog in heavy chop, Kawi is the ski to own.
    If you frequently ride on glass to mild/mid chop....I prefer the FX.
