ya don't run it without a fuel system, that build on a stock ecm will make you bike run way too lean and will cause you major issues

RE: Backfire through carb when cold

So it's not a carb? If it is a jetkit with lighter spring and drilling the vent in the slidewill allow the slide to raise faster and that will go away after a dyno. If it is a FI bike, I am guessing because of the talk of a race tuner, it should be taken care of during the dyno tune. No worries.
