My Polaris 800 has about 100 miles on it. When first started up in neutral want to stumble a lil bit. Let it warm up a minute no stumbling in neutral. After I let her warm up to operating temp and gas it from a dead stop want to spit back thru the intake a lil bit INTERMINTLY and not all the time. I can taks off slow till I get to around 2000-2500 and gas it no spitting what so ever. Took it too dealer and he replaced the plugs and adjusted the TPS. I am open for any and all suggestions on where to look now.????

 

did it throw a code at you? is that why they adjusted the t-sensor on the intake? is this the bike w/ the key way in it adjusting the timing? just wondering if would all of sudden have anything to do w/ the computer timing being off? didnt get any water in the tank? howed the plugs look when they replaced them?

 

My 08 800 behaved similarly and it was a loose negative cable at the battery. Make sure they are tight.

 

that is a good point where these new bikes need a 12.8 volt charge all the time to run correctly.

 

No codes. Plugs were black that they replaced.Took timing key out back to stock b4 taking back to dealer.I drained the gas and replaced. This spitting is so intermint???? Checked the battery conection gonna check all the grounds and the positive on the solonoid etc. Im lost if I can not figure out I guess its back to the dealer again????

do you think the the t-bap sensor has got moved and check the connections real good. i was reading the manual about the efi and it says about 80% of problems are due to bad connections on any of the componets. worth a look.

 

t-bap sensor? TPS throttle position sensor?
