The bike stalls out (shuts off) when it's idling, upon deceleration as I'm coming to a berm, a stop sign or going downhill. Basically, any time I'm not on the gas, I've got to pull the clutch in and blip the throttle to keep the bike from stalling out / shutting off. And it doesn't bog, no burping, no tell-tell sign it's going to die, it just plain shuts off. (so quickly, as a matter of fact, it'll lock the back wheel up before I get a chance to quickly pull the clutch in! -dangerous!!!) I've got the jumper connected, it's in Race Map II, I've decatted the muffler, I'm running 91 octane, the air filter is clean - the bike runs great (it's an absolute BEAST, actually) it just won't stay running! I've even adjusted the little idle screw on the EFI (which didn't do anything but make it idle a little higher while it did decide to idle) and it would still die as explained above. ***?!
