hay guys, it's the sauce man again, and i'm having some problems with my 06 RMK 900. now the last time posted a thread I requested some help on mods that I could do to give it more power and lighten her up. Well, I took a few suggestions I bought a timbersled airbox, a snowstuff rumblepack, and a clutch kit. Now, I am having trouble with keeping plugs, it seems they are carbing up, and it's getting expensive. Now, I tried cleaning my exhaust port and the guilitine now on a start up her RPM idles at 900 RPM when I tap the throttle she goes back to the normal 13 and 1400 rpm, then she seems to work fine. When the RPM's drop again there is a faint clicking sound coming from the console, from the gauges. When I try to put her in reverse she justs shuts off! I need Help!!!!!

is this happening after the sled is fully warmed up? i have seen the reverse functions act like that if the motor isnt warmed up, try blipping the choke immediately after putting in into reverse. might help.

no this isn't the problem, it is a cleanfire injection system , no chokeing system with this,, and it's doing it on start up, when it's warm or cold.

Check the oil pump cable. They are famous for breaking and your oil pump will spring back all the way wich over oils the engine as a fail safe and fouls plugs.

Sounds like the same problem my cousin had on his 06 900. He changed the tps=problem solved. I think the clicking noise was just the gauges re-setting, watch your tach, it will go all the way down and then re-set and i think that is what is causing the clicking noise. I could be way wrong......

TPS..its usually 80% of the problem..from idling to bogging at higher rpm..

look at your throttle bodies..there is a small sensor on the exhaust side of the throttle body..that is the TPS (throttle positioning sensor)..they can be out of adjustment or the wiring harness will break, they have crappy wiring from the dealer..i would have the dealer use the digital wrench and check your settings..but i would replace the TPS wiring harness regardless (you have to remove your tank to replace though)
the wiring harness is not shown in teh parts diagram for the 900..get one off of an FST P/N 2203165 -$35

also if the reverse doesnt work (ie.. the motor dies) this IS your problem..

Yep, that'd be my bet. The little connector between the throttle body and the oiler is a piece of scht... pain to get out too.

Hmm, could be something in the gauge, that's the only mechanical part up there. Sure it's in the dash and not with the engine? (Unplug the two connctors to the hood and see if it goes away...)

Throttle Position Sensor. Black thing with a 3-wire connector on it on the exhaust side of the throttle body.

Good luck with that.... lol... if you find a copy let me know. You'll need hardware to connect your computer to the sled too, i've started a few threads on obtaining information on that and there's virtually no data on that. Polaris keeps that stuff locked up tighter than a virgin.

Not really... the weak part of the wire is at the connector. I pulled the wires out and soldered new wire onto the pins, then cut the wires about 6" from teh connector and soldered them to the new wires. Total cost: 30mins and some leftover automotive cable.

I'd love to pull new cable between the ECU connectors and the rest of the sled, but that requires pulling the engine out.

If you sled idles below 1000 rpm it doesn't produce enough voltage to run the gauges. It will go off and on and you will hear the clicking sound. Also your reverse won't work. this is normal. You have to find out why its idleing so low. this could be a number of thing and the most common would be tps or tps wireing.

k guys, thanx, for the input, i got a good feeling that it is the tps, or the ecu, so i'm off to corner brook tomorrow to get her checked out with the digital wrench at the shop. as allways this is a great place to get information.
