Default Sled keeps bogging out.

This Is for a 1992 Polaris 500 SP EFI so first let me say the carbs wont be the problem because Its a EFI. Well then heres my problem last year when I was riding about thirty mph the sled would start bogging alot and when I gave It gas It would keep on bogging until It went to zero mph but when I gave It gas It would bearly move and all It would constantly do would sit there and bog as If It couldnt move and kept bogging. Well the only time It wouldnt bog was when I was going about sixty then It would ride normal. But If I went under that then the sled would sit and bog every second and wouldnt let me drive for ****. I replaced the plugs but the problem was still there It would Just sit and bog when I would try to give the sled gas and when I was riding would bog down to zero mph Idk wht the problem Is then when I was at zero and I did give It gas It would sit and bog. Then.

It sounds like it might be running on one cylinder? Have you replaced the plugs? Checked to see if one is running much darker/wetter than the other?

It might also be clutching. If one of the clutch springs is broken the clutching might be unable to keep the engine in the power band it's designed to run in. That might let it shift out too quickly, kind of like taking off in high gear with a car - gutless....

If that's not enough to make you wonder, it could also be a fuel problem.

Point here is it could be many different things. If you want to proceed on your own without throwing a bunch of time, money and parts at it without rhyme or reason, you need to find some information regarding maintenance and troubleshooting and start studying.

X2..you need to narrow the field from a fuel problem, electrical or clutching. First be sure your battery voltage is right up there. Any lower than 11v and these sleds do weird stuff. If you haven't replace either clutch spring in a long time ....change them. Inspect the secondary clutch for worn buttons and any sloppy operation. Same with the primary clutch...worn pins, rollers, buttons with contribute to erratic operation.

The sled has 1500 miles so Idk If a clutch would be bad yet but Its a possibility. Maybe It was to hot out because of the coolant coming out all over. But Idk. How would I check the fuel.

Another basic check is to check compression. A worn engine will bog on takeoff.
