    Question 95" sl750 rpm issue

    Ok, I have a 1995 polaris SL750 have done the TRIPLE fuel pump upgrade and carb kits. It was running good but one day RPM went up so i had to re SYNC the carbs got it idled down 1400 in water BUT the RPM jumps around to 1400-1600 at idle and when im running down the river at say 5500 it jumps around from 5500-5580 im stumped because plugs look amazing and its running 51.6 MPH and im 6'6" and 300 LBS any IDEAS

    #1 Sorry to burst your bubble but your ski don't run 51.6 MPH stock, and especially not with someone of your size, not that I think your lying your speedometer is though

    #2 I can't tell you what RPM but I'm almost positive that your ski should be turning at least 5800RPM to 6000RPM at WOT.

    Not really sure what EXACTLY your question is here......? Are you worried that the idle is too high? That you can't hold a steady RPM? Need clarification please....

    I dose hit 6000-6100 wot. I'm just worried about it blowing up rpm jumps around a lot when I hold it steady.. and it seems if I hold it steady for 15 sec or so bumbles and stuff like lol example what it sounds like (mmmmmmmmmmmmbubbmmmmmmmmmbub) if you make that noise that's what it dose at a steady throttle

    Not sure I would worry about Idle speed bouncing around. Alot of different factors in play while resting at idle. Air bubbles, current changes, load changes, fuel changes, etc. both of my skis fluctuate as well.....

    I am lucky to keep my ski within the same RPM +-200 RPM much less 80..... If wash and plug chops look good, should be fine....
