    Possessed SL750

    uhh ok this is to all who said there is NO limp mode on the 95 SL750

    In Fact mine Does and I found out after after some tests

    I Purchased a new E-Trax GPS and the Ski would only PEAK at 4700rpm/32mph
    upon messing around I pulled the sender jammed a neodyne magnet in the sender to trigger the gauge to say there was more half a tank full. the ski all of a sudden kicked me in the butt and gave me a shock it would peak roughly 7200-7800rpm which ran average 52-53 mph and peaked at 61mph..

    what is the supposed RPM range of a 1995 SL750 I do know it should run roughly 47-53mph

    You must have a 780 CDI in it. The 650 750 did not have limp mode. What is the PN/writing on the CDI?

    I'm not sure about the 750 but I know the 95 650 has a buzzer and no limiter ability.
    The 750 did go to the MFD that year, hmnnnn.

    Mine has that Oval type 8 pin MFD.. All I know is when the tank is over 1/4 tank the sender shows one bar, when its 1/4 under the gauge will bounce and show activity and thats when it kicks in and goes into high gear..

    Infact, I was thinking it would need 1 hell of a port job on the 750 to turn those r's w/ the pro cdi.
    What the hell is in that boat?

    I thought the 750 was only rated to 6100RPM and 52MPH. Damn I need to do some more tuning once I get this beast back together. 7300 RPM would fly

    LOL from what I can tell is its the stock Fuji Polaris 750 Motor, it has been worked on numerous times, and the PTO Wire/coil has been replaced with an unknown one due to the sheathing around the wire itself is plyable and I was peeling it back when i was going the 1/4 wire cut aswell as the wire printing is totaly different but the core is teh same diameter

    This is a pic of the Shiney, clean, 99% rust free motor with 126 hours on it hehehehe

    Something is amiss Feral. Your 95 has a reserve setting. Only limp mode was present on skis that didn't have the reserve. That started in 95 with the SLX 780.

    Your numbers need to be verified. There's no way that ski should peak those RPM. The rev limiter is set at 6700, even a 780 CDI with the loop cut should only reach 6900 RPM. Only the PRO CDI or an aftermarket/reworked CDI could allow RPM that high. Is your MFD working well? It was more than likely 62-6800 RPM.

    Top speed of that ski would be about 52 MPH in stock form. I can't imagine that ski getting 61 MPH on the GPS.
