Hey I have a 2006 hayabusa engine in a sandrail. I recently got the sandrail back from a tuner in Las Vegas NV. Neither they nor I have come across the solution to our problem.
We can "putt" around all day and part throttle stuff but as soon as we do a nice hard pull and let off the throttle the AFR immediately gets LEAN and the motor dies without returning to idle. Then after it dies the motor will not start up and idle or perform normally unless you let it sit for 5-10 minutes then it will run perfectly fine until another hard or semi hard pull.
Does anyone have a clue what I can even suspect or check out or anything? We are kindof at a loss. The motor is turboed running around 8psi boost. Low compression pistons forged rods and cross cut trans. Garrett g28 turbo. The fuel pump is sufficient I will get details on it tomorrow.
What could cause this to happen?
I am at a loss and I haven't been able to go out and play with this thing for months now. We need some help!!!!
