I have a 2017 250l (street legal version) that dies every now and then which shouldn't happen being that the bike has about 4500 miles. It seems whenever i chop the throttle, shift down or pull in the clutch to coast it dies. About a month ago i filled up at a gas station that had all their gas tanks filled with diesel and my bike threw an injector code. I replaced the injector and cleaned all the fuel lines/ gas tank but I didn't put in a fuel pump. It doesn't die very often, maybe 1-2 times a day or sometimes itll run fine. Also i dont run a baffle and i have a power commander so i think that i might be running rich and that might be the problem. When it dies there ia no engine code that pops up and i can start it back up no problem. What do you think the issue is?

Did it have the problem before filling at this station that had diesel cocktail?
Is the idle speed correct?
Is mixture correct at idle and off idle?

I can't remember, i dont think it shut off like it does now however I installed a power commander in the process of doing the fuel system so it could be that it was running way rich. I tuned it to run it a little leaner a earlier and hasn't given me any problems. Maybe it was running to rich still. It makes me wonder though cause if it has a bad fuel pump why would it be able to run good for a day with no issues but once i chop the throttle it shuts off. It does it very rarely, maybe 1/100 times.
