Gen 4 trouble with stalling out

I purchased a gen 4 2011 zx10r. Bike came with a Bazazz and dyno map, full yoshi exhaust, and extended swingarm, and flashed ecu. It was too much pricewise for me so they took off the bazzazz and swingarm to lower the price. Ive noticed the idle is terrible and it has cut off twice. Once taking a slow turn with the clutch in, and once at a redlight. Is the full yoshi exhaust not going to work well without the bazazz? First gear ive noticed some sputtering and the exhaust sounds like snap crack pop. Please help!

I don't think yosh offers a full exhaust for the gen 4, Just the 3/4 or whatever they call it. The bike shouldn't have any issues from the exhaust. I'd look into the plugs that the bazzaz plugged into and make sure they are all fully connected. Seems like something like that may be you issue. The exhaust is most likely accounted for in the flash anyways so I don't see it causing any issues.

Who did the ECU flash? Do you know? Did you test ride or at least start the bike with the Bazzaz on there before buying it? Does it run fine everywhere else and not just at idle? I'm wondering if it might be the flash. If it was some generic map that was thrown on there, it might have a fueling issue down low. I'd try to talk with the previous owner and see if you can get some details on that.

Unfortunately the idle on the G4 is computer controlled through an idle control valve, so it's not adjustable unless you reprogram the ECU or modify the throttlebodies.

I may not be perfect, but at least I don't ride a Suzuki.

They changed the spark plugs and took it apart and im guessing messed with the idle thru the throttle body, Ive had it back one day and it seems to run better. Im not sure who did the ECU flash. The bike has 3000 miles, didnt think the plugs would go bad so soon. I never test drove the bike lol.
