    Rxp rpm issue ?

    Hi has any one had this prob i just changed my supercharger clutches to the new seadoo ones im using a ckit with 8650 ecu and 15/22r prop so after riding for about 2 hours ski was running butifull at 8500 rpm then wouldnt go over 8150/8200 so i let it rest abit then when i fired up it wouldnt start had to have 3 goes at it when it finally started it it ran like it had a bad coil or spark i gave it a little gas and whent back to normall at only 8100/8200 rpm do you think bad plugs will cause a loss in rpm thanks will change them soon bad weather here this week so waiting for a good day to go test again
