I have now some work on the engine and I am breakin' in.
I have port&polished head, high compression pistons (stock bore) and TPUSA 813s cams. I am using a good 2in1 exhaust system.
The jetting is as follows:
air screws: 3/4~1 turns from closed
needle e-clip: middle position (out of 5)
main jets 142.5
I am currently using UNI foam pod filters UP4229
I have activated accel pumps (using leanest nozzle #50) but I haven't still tested WOT since I am breakin in the motor.
I would like to know your configuration and your experience with the accelerator pumps activated on these motors.
Thanks a lot.
BTW here's a photo of my bike:
