I am looking to buy a new to me quad and one of the ones I am looking at the owner moved from Colorado to Virginia. He tells me that it needs the fuel system adjusted for the lower elevation of Va. Anyone ever had to do this on a fuel injected quad? I know you have to do it on carbs, but fuel injection? I have not gone and looked at it yet, I wanted to get some opinions first. It has 600 miles on it and it is a 05, so you know it has sat a lot. I just want to see if this is something that is common and an easy cheap fix, or if this guy is trying to sell this thing with a screwed up fuel system probably caused by sitting with ethanol.

 

There should not be any adjustment needed, the program will adjust the air fuel mixture on it's own. We had an 05 700 and rode it in Florida and the mountains of Tennessee with no adjustments.

 

Yeah that is what I thought. But I did not know if maybe in some conditions the computer would need tweeked. Thanks for the info.

 

I went and looked at this thing last night. Nice ride, but it does not idol without stalling. Seems like it is running about 2-300 R.P.Ms low. If you hold the throttle open just a little runs great. I did notice the throttle cable seems to have some slack. The guy says it just started to not idol. I told him to try some throttle body cleaner and maybe run some seafoam through it. Maybe even suck all the old gas out, and put in fresh. I was hoping maybe some old gas got to it, says it has never had ethanol but I never trust that. NO fuel injection idiot light is on.
I would be interested in picking it up for the right price, but do not want to get into a mess.

 

If it runs and starts good and the axles and bearings are in good shape. I'd buy for the right price. There is a idle adjustment twist nut on the throttle cable close to the throttle lever

 

Bought it, took it home, sucked the old gas out, poured in some seafoam and fresh 90 octane Rec fuel, sprayed some throtle body cleaner, ran it for a few minutes, runs great.
Sometimes things just work out.

 

GREAT now enjoy and be careful
