Polaris 800 EFI Sportsman Touring (Sputtering Problem)
#11
latest update
Latest update. I took apart my sportsman 800 efi today. I took the spark plugs out and they looked good and clean. I checked the T-Bap sensor and traced the wires and it was clean and no visible damage to the wires. Next i took the throttle body off. The rumor about the ethanol gunking up is true. When i took the throttle body off there was black gunk on the engine side of the throttle body. I cleaned the throttle body out and got to thinking if that gunk was on my throttle body what do my injectors look like? We all know if the injectors were gunked up it would cause a sputtering. I didnt make it to the injectors yet. Just sharing what i have found so far. Any other suggestions would be helpful. Thanks

What does Sea Foam do? I am pretty new to Atv 's when i ask this but mine does not have a fuel filter on it. I got a direct line to the injectors. Should i look at trying to place an in line filter on my atv? I also thought about running some 103 octane in it. Would that be ok or would i burn my rings up? Thanks

I have 07 Sportsman 700 EFI that seem to be having a problem with my right side spark plug wire. I have an issue with my machine acting like it drops a cylinder and then back fires and coughs through the airbox. I changed my plugs from Champion to NGK's but just the other day the same problem occured. Called Polaris and they just want to soak me for Labor rates. If you find something for sure please email me. I will do the same.

not 100% sure, but was thinking there is already a fuel filter inthe fuel tank. good to know about the black gunk you mentioned w/ this crap fuel as i will next year put some fuel injection cleaner thru the bike. as far as putting higher octang in the tank, it's a pretty much a wast of money as the higher octang is more high performance engines(which these are not) w/ high compression rates. although the higher octang fuel is known to last a lttle longer in loosing points when the fuel has been sitting. what happens to the ethenol gas is that the shelf life isn't very long and the octang level starts to drop very quicky. example if you have 89 octang gas and it's been sitting for a couple of weeks it might be down to 87 octang level when you go to use it. this is why it's so important now to use a GOOD gas stablizer. imo
