    Some issues with my 300x

    Had checked these before when i bought it but they came loose, Ski would not start today thought it was the battery but after further inspection they were finger loose! So loose they burned up the red boots.



    Max rpms is only 7,350 with scom and stock ecu. Checked all hoses and clamps and my intercooler is super clean inside. Going to replace spark plugs and see if i get back to full rpm again. Im using the NGK PMR9B they can be found on amazon for 13.00 each instead of 28.00 at the kawasaki dealer.
    This will be my 2nd set i have 30 hrs the ski.

    Im having some weird feedback when cornering at high speeds seems like all i can get out of it is 50 mph when turning real sharp and after i straigthen out the ski hits top speed. KSS is disabled

    those terminals have been reported before. should have been tightened in pre delivery sounds like you have some serious cavitation. thats your cornering problem.

    are you saying the speedo will only read 50 or you can only manage 50mph with the throttle held wide open?

    Speedo only reads 50 at WOT in tight corners. Is the speedo lying? im full throttle and dont let off but you can feel the ski slow down when its turning hard then speed back up when its straight. Im running the stock grate with a TBM ride plate

    the exhaust filter and gaskets were just replaced and this was my first ride on the new one. So its not clogged or installed wrong i can assure you that much. In terms of the speedo i understand your point but i can physcially feel the ski slow down and speed back up on the straights and thats with never letting off WOT

    i doubt its cavitation, a car will loose some momentum in a corner even if your flat footin' it, a ski will do the same.
