    Unhappy Exhaust Causes Secondary Problem STX-12F ....

    Any help here would be greatly appreciated,

    I have a 2003 KAW STX-12F with the riva free flow exhaust installed, The hose clamps with the worm screws must have worked there way free a bit and I had an exhaust leak, with the modified oil exchanger intake being somewhat close to the exhaust some water got into the oil exchanger and casued the oil to go milky, got it home, changed oil 3 times then final change with new filter the ski ran great. Put an extra hose clamp on the blue coupler and made sure all clamps were tight. I took it out again and during the 10 min test drive one of the hose clamps broke and was in the bottom of the ski, I think I had over-tightened it, I tightened the two remaining clamps up and made it back to shore but I was unable to keep the ski running at idle. I got it home and changed the oil 3 times (AGAIN) and the filter since it was milky, but now the ski will NOT stay running, it will turn over and start but immediatly cuts out. I checked the plugs and they all have spark. The engine will sometimes start and run but at like 500 rpms and rough, when I gas the engine will REV high then drop, REV high and drop, REV high and drop untill it stalls out again?

    I tried to get into the Diagnostic Mode using the two buttons on the dash but it will not change the dispaly or flash any type of code so no help there either?

    What would be your next step in troubleshooting this ?

    Thanks all

    Check compression. What do the plugs look like?
