'06 GPR Idle trouble????
The idle on land wont keep engine running. RPM drop to ~850 and stalls. It will run if I apply throt. No backfire or gallop just slow. Initially threw a #15 "eng temp sensor" but just once.
-history, engine rebuilt at 100hrs w/throt cable recall. Break-in ran great. Saturday I ran 80 miles and the ski was brilliant. Ski was hosed down and Sunday AM was the idle trouble. I could only flush ~ minute.
-pulled the plugs & compression is spot on. New plugs same problem. Third set same. I'm waiting till dark to look for spark issues.
If spark looks good how should I proceed?? (snatch pipe & TBody??)

i doubt JP did it. . . well. . . then again. . .
Did you spray the plugs and boots with wd-40? maybe its just some leftover saltwater making it arc to the head?

I had strong spark in all 3 with open ciurcut and no spark loss with engine running.
It starts and runs when applying ~1/4"-3/8" throt pull but there is no noticable slop in the cable and they snap shut. Throt cable is firmly mounted on bracket.
Any suggestions are welcome. ie:
-did a squirel move in to your waterbox overnight?
-did the #2 or #3 wire harness fail from the ride home yet not durring the 8 hours of abuse before?

It sounds like one of the cylinders isnt firing. I had the same problem with my 07 once. I had to take the CDI box off and make sure the connectors were snug to the coils. I also had a buddy with an 06 that didn't tighten his stinger so it vibrated loose and the bolt that holds the stinger to the head punctured the spark plug wire and caused it to arc.
Basically, since you ruled out the plugs I would check over the wires for splits or bad connections

I just went back and reread that you hosed the ski down. Did u spray down the engine at all? if so maybe water got into a connector. If its still acting up then take apart all of the connectors, spray them down with electronic cleaner then apply a little bit of dielectric grease and connect them again.
You also said the throttle cable was firm to the bracket, are you talking about the one by the throttle bodies? if that vibrated loose that would cause that problem also

Every electrical problem Ive ever had goes back to that big connector... Except the time my rectifier went on fire... But thats a whole different story..

My ski always does this its the big grey plug where the efi controller plugs in you must have got some water in it.
Pull it apart and clean it out and it will be fine.
