1993 XP RPM Issues !!

[raptorrider660]

Hey everyone !!

I have read through the forum and there is a lot of good info here !! I purchased a 1993 XP just to play around with in our local river and I ran into some problems!!

It seems as though at times it will not get up past 4000 RPM, but some days it ran perfect!! I have the carbs cleaned out (2) times and the high speed jet all the way tight and the low speed 1-1/2 turns out. When it will not get past the 4000 RPM, I have opened the seat while underway and pinched the fuel line and it would kick off and get up to ~6000 RPM. I have read about the "rectifier" as a possible problem, so I unhooked the red wire in the computer box and I was going to try it out today. The person who owned it last did the oil reroute trick to run on premix and he also said that each cylinder had ~130 PSI, one does have 130 but he front one check out to have only 115!! I was going to run it a couple months before doing a top end just to be sure its worth doing. I also have the fuel lines running directly from the tank to the carb. I was thinking it may have been a problem there??

Does anyone have anymore suggestions?? Thank in advance :cheers:

Ok, I did find that the High Speed jets were not all the way screwed in !! I screwed them in and took it to the river, and seems to be running a lot better now!! But it still bogs down only when I turn?? I'm going to replace the spark plugs because they were pretty black from the high speed jets being too rich and see what happens!!

Anyone else might know why the ski would only bog down when turning only??
