Last weekend was out for a ride with no problems. Today i go out and start it, it revs up to 3000rpm and then it droped to about 600. When i give it gas it just boggs but doesn't die. If i pump the gas the revs will come up to where i have power, but as soon as i let go of the gas it will drop back down to 600rpm. I put mew plugs and still the same thing. Would a low battery charge do this or maybe stator????????????. Not used to working on EFI.

Yes a low battery charge will do it. That style efi will not run if the battery is dead, missing or low. That's why I gutted my bro's EXT and turned it into a carb'd sled.

Was working on it today and the battery is fulley charged. It seems to be idoling around 1200rpm now. I noticed that after a run today when i shut it off there was a hissing noise on the pull cord sided. Could this be a seal and causing my low revs by sucking in to much air.
