I had a 900gpz with the inlet cam installed wrong. Was 1 tooth retarded.
The bike started and run enough good. Maybe a bit sluggish in "slow rpm under load acceleration"
The big improvement was the gear shifting. With the engine timed in the right way i can barely feel a huge improvement in shifting the gears. So much smoother, especially when downshifting.
I cant understand how is this possible.
Any expert?
