I am stumped. I've been chasing a weird stumble in my 07 600 rmk 144 for two years now. It seems whenever I try to go from maybe quarter to full throttle, the machine will basically sound like its missing, its hard to describe, but it won't go past like 5 to 6k RPM. It isn't really an issue on the trail (though it will do in like a drag race scenario).
If I'm going uphill in powder, if I stay on it with it stumbling, it doesn't clear up, it just keeps doing it until I either get stuck, or let off.
I have put the leaner jets on (.9 air, idk if Iput the 40 pilots in) adjusted the air screw in , the plugs appear brown. I just put new clutch springs, top end, and slp pipe and can on at the beginning of the year. Tps was adjust last year.
Anyone with ideas? I'm looking for anything at this point.
