Hi everyone, I just purchased a 02RXDI last week from a repair shop out of state. The guy put it in a test tank before purchase and it seemed all there. Bring it home and back it in the water on trailer and let it warm up. Rev it a couple times and got 7200rpm like manual states. Take it off and ride it for about a minute and a half at WOT at 6800rpm and 40mph. That’s not right for a 951. On the way back to the dock it would start fluctuating rpm between 6800 down to 5000 instantly and fall on its face for a split second then pick up and drop again. Eventually it stalled out but fired up instantaneously but would have to work the throttle to keep it going and couldn’t get over 3800rpm. Got it home and started thinking about it that the rapid decrease in rpm would be electrical so I pulled rectifier it was an aftermarket one which I know is a no no so I ordered a oem one from WestSide Powersports. Tried it again today and still only 6800 rpm at 40mph. The fluctuation seemed to not be there but I only rode it maybe 3 minutes since I know it’s still not right. I have not checked fuel pressure ( I assume it’s good because wouldn’t rpm drop gradually if it was loosing pressure?) not sure what to do next. I’m a little in over my head with this direct injection. Any help or guidance would be appreciated. Also attached is A picture of the plugs. It has a total of .8 hour since I’ve owned it and these plugs were new when I bought it. Look a bit lean to me?
