250 ultra running rich
I have a Ultra 250x 2008 119kph on gps which I purchased new for $21500 on a trailer about 70hrs on it never really missed a beat with until now, I had the pulleys changed and pop off blocking plate installed for more boost, intercooler and 2010 impeller shaft mod done , when the work was done the jet-ski shop could only get 3 spark plugs out and the fourth rear one stuck in the head they said it would probably would snap off and as I was on holidays and 20hr's from home I took the ski away, now after riding the ski would sometimes hesitate when hard on the throttle from idle which seem to be getting worst the more I ride it, so in to the shop close to home for service and new plugs, which one snapped off damit off with the head now all back together but it's still running rough at idle and really rich, blowing black smoke what would be causing this? anyone had this happen to them? Cheers and thank you for you help

If any electronic sensor is unplugged or not sensing the usual value, there should be red "FI" light flashing on your dashmeter. No "FI" light means most likely not a sensor related issue.
Pull out the spark plugs (again) and check their color. Post pics here if possible. It could be a mechancal issue that sensor can't detect.
BTW, shouldn't the 2nd shop take a look at this problem since they are the once who worked on your ski the last time?

119km please explain? If possible could you list all mods, many of us don't see even close to that with more. I'm tipping current advantage as well. Bloody fast dude, and you rekon it's rich?
