EFI measures airflow and gives fuel to match, Making simple changes like this will not adversely effect it. On carb atv's pressure changes from free flowing exhaust and intakes will cause a lower suction across the jet and make lean conditions. Works the other way also, If your intake is really dirty it makes a higher suction across the jet giving you a rich condition.
So, it wouldn't be hard on the quad to run without the EFI controller? I'm definately going to get one, but if I can run it fine without the controller for awhile I'll go ahead and install it right when I get it.
