I have a '94 700 EFI doing basically the same thing. It likes to foul the plugs. Possible oil foul. I have yet to go through the fuel system, but it could be anything from a dirty injector to the pump or sensor sticking. One of these might be your issue as well.

Boging out

I have a ī93 Wildcat Efi and just measured the fuel pressure and got 2,1 bar = ca. 30psi. Itīs very easy to measure the pressure, just take the hose off were it connects to the rail (clutch side and stick a meter in between). If you donīt have a meter you could also take the hose off the other side off the rail and put a bottle under it to see if the pressure regulator is working. You should always be getting some gas flow through the regulator if youīre getting enough pressure. The meter of course would be best.

My best from Iceland, Iceeman...

just to ask a stupid question , but is it possible if the fuel is there just a weak spark ? could this be as simple as a bad coil?

The pickups on the tank for the fuel can get clogged.
You would have enough fuel flow for low to mid rpm operation, but not enough for high speed.
Has the sled sat for any extended time (year or more without operation)?

Yep the smart valves wont let water pass but will get clogged! Also the fuel pump has a crimped on hose fitting that came loose on mine! Good news is that Auto Zone crosss ref my pump by the numbers on it and they had one in stock for like $75! Just had to use a different fitting on pick up!

try putting some Injector cleaner in the gas...and on my buddys 700EFI hes running a higher Octane...u can probably even put a dash of Oil in the gas tank for some extra security against engine failure, and maybe a possible small engine tune up...i run it in every tank of gas i put in my jag along with a dash of injection oil

No mixing oil with EFI as it can clog the smart valves and injector nozzles.

I will use some of your suggestions when I have a look at mine, and let every one know what I found. I hear that there is a computer program that can scan the engine, and that the wiring harness is available through Arctic Cat. Is anyone aware of such a program?

No, the oil is injected directly into the lower block under the throttle bodies.

Dwayne also check the injector sensor. I had a similar problem and I found that the sensor was loose.
