    I posted the service manual page for compression specs a page or so ago

    Keep an eye on the oil and if level rises then get it changed

    No help but my 08 sho running a solas 13/22 idles at 1500rpm on the cluster when on the water tops out at 7300 ish now and 67mph since I added a worx grate was 69/70 on stock grate

    ski has straight exhaust, stock waterbox, ribbon delete, worx throttle body mount, aftermarket air filter in stock airbox, as well as the solas prop (thinks that’s everything so far) R&D ride plate and sponsons soon hopefully then maybe a remap.....

    I bet your throttle body body is stuck. Mine froze did the same thing.

    friend had a 2014 fx svho. similar problem, could not get to speed, but not supercharger clutch, etc.

    eventually found the source of the problem was the throttle mounting plate. the rubber had melted/deteriorated and leaking air. take it apart and check that out. could be the source of your problem.

    while you have it apart, do ribbon delete, and tap the manifold for a future addition of BOV.

    throttle body mount failure is my guess also

    Thanks, I'll get that done and like mentioned do a ribbon delete while at it.... I'm on vacay currently for next week (due to stress caused by the FX lol) but have a dealer date booked for 23rd of this month to hook this thing to the computer... It will be interesting and wallet slimming... Thanks again!
