Calling all engine GURU's (riddle for you)

[sleepy]

Ok guys, I’m tired of pulling out my hair ( I’m actually bald). I have been having a problem with my bike ( 2000 turbo Busa) since doing my re-flash. LET ME MAKE THIS PERFECTLY CLEAR…THE RE-FLASH IS NOT THE ISSUE! I got my bike to fire, but it seemed that it was really lean. I installed a LC-1 to monitor the AF so I could see problems coming. Ok, I’ll admit I changed my cam timing, please know that I am not a novice and I have done this a thousand times, I’ve checked it a hundred times since, and I know it’s right. (I think,… starting to question my skills!) The bike started to kick back on me! It will turn over 6 to 7 times then…wonk! 6 to 7 times…wonk! Now I thought it was my battery…new one installed, same thing. To make matters worse, after I put the new battery, It kicked back and broke my DAMN cases!!! Well, new cases, timing good, new starter…SAME ****!!! If I unplug my injectors, IE no fuel intrusion, bike cranks over fine. Plug them back up WONK open the throttle and it spins over fine.
WHAT THE ****!!!
Somebody help!
Pleeeeeeeeeeeeeeeeeeeze

Checked basics like fuel pressure, one way clutch is on the correct crank spline,
It has been running ??
In editor the injector compensation is correct for your injector size ?
are you running a pc or is editor doing it all?

Where is the IN cam degreed at?

Maybe it sheared the key and is out of time?

does it have ajustable cam gears? check to make sure the gear isnt 180 off and the cams arent following each other. ive personally had this happen.

Check your injectors and make sure they are not stuck wide open filling up the cylinders for a ugly kick-back.
