2004 GP1300R - Bogging off idle, and possible misfire or arcing in rough water or ...
I have been chasing this stupid issue since I bought this thing in early Dec 2011. She runs great mid to top end in a straight line. New plugs, new impeller, new wear ring, Riva top loader grate and pump seal kit.
If I start jumping waves or spinning her around quick (like 180s/360s) she seems to bog/misfire for a few seconds, then clears up and hauls a$$ again. The engine definately changes tone when this occurs, so I am thinking spark related? Or fuel starving? Not sure. Seems to stall sometimes at idle as well, either on water or in driveway while flushing. I will try to get video of this soon to help get visual/sound conveyed better.
When running, if I touch one of the plug wire boots, should it shock the holy crap out of me? Are they not insulated enough to prevent a harsh shock? I expected a little bite, but nothing like that. Maybe need new wires?
I was looking at the MSD wires with retainer clips on Riva's site. Opinions?
Would love to get her running perfectly for summer. She runs great on top like I mentioned, reading 65-73 on the dream-o-meter depending on the waves and wind. Just have to feather off the line til about 15-20 mph then I can hit throttle WOT and she flies! Not sure if the off idle bog and the possible misfire issue are related either.
Any help is greatly appreciated! Thanks in advance!

Definitly not supposed to shock you. Check for cracks and replace if needed

That's what I figured. Any opinions on the MSD wires from Riva?

Also...........Inspect your plugs and make sure the Porcelain is not cracked. I had this happen in 03' , it drove me crazy!

Yes, been chasing this issue since I bought it. Put new plugs in as an attempt to start troubleshooting issue.

Checked plugs at lunch today. No cracks that I could find. Wires look ok, no splits. Ugh!!!

If you are getting shocked then electricity is coming from somehwere. What about the dialectric grease on the plugs and wires. Sounds like the water is causing a short soemehwere. do all the wires shock you or just one? If only one replace at least that one
