I know the EFI will operate better at different elevations unless the carb is rejetted, but I will not be riding it too much above sea level.
Is there much difference in performance between the two?
Has one been more reliable over the other with Polaris?
My local dealer has a '07 500 with EFI and a '08 500 with a Carburetor both at the same price.
Thanks,
Mark

I guess it would depend on how you ride. It's like this. If you swamp a carb atv all you do is dry it out, put some new oil in it and flush the carb and your good to go.
With the EFI............well..........that won't be the case most of the time. That hole in the injector is VERY small. Any speck of dirt will clog it and then your done.
I thought EFI was the way to go years ago. Now...........I would rather have a carb in the dirt and water. EFI is still too soft for me.................."yet." Do a search on this site for EFI problems and you will see what I mean.

efi or carb ? they both have their pro's & con's efi will have a little more responce on take off . but carb is alot cheaper to maintain. Their are a lot less electrical componets to have to worry about. Efi it the best for cold weather you dont get that spit & spudder. I have always had carb's and never had any trouble. Iv'e rode in the mountains & lowlands. I now own a 700 efi haven't really had a chance to try it out.( just in kentucky) Hope this helps.

RickCJ7............"You never need to work on EFI".................Do you drive a car or truck?
Yes their all good when there new!!!...Cars ,trucks ,ATV's ,etc...
You can't say "never".............Quads do get old.
How old is the oldest EFI quad out there right now?.........Few years?.....
Lets give it some time and then we will see if no work is needed!!!.....Just my view.....Caper.........

Everyone got scared of EFI when it came out in to 80s. Now it's almost imposible to find a carberated car on the road today. It's the way of the future. Now saying that, Polaris's EFI system is not very complex. It only runs off a set paramiter like an open loop system. For a certain temperature, throttle postion and altitude it allows a set amount of fuel. When you change airflow with intakes and exhaust the computer will still use the same fuel as stock. This COULD lead to a lean condition. Whenever the manufactures want to spend more money and up the costs of the machines they will go to a closed loop system with a Mass-air flow sensor and an 02 sensor or two. This will allow mods to be done easier without programmers and such.
As a mechanic I know first hand NOTHING lasts forever. Sensors and modules and wiring are going to be problems ALL the time. But hopefully no one has any problems and happy trails for all [img]i/expressions/face-icon-small-smile.gif[/img] LOL
