Did you just do a baseline check for the hell of it, or did you take it to the dyno to finetune the carb and whatnot?
36Hp / 50NM
DIN power / DIN Torque.
With the open airbox it GAINED 2hp!!!!!
I adjusted the mixture screw a little bit since it was running a little lean, other than that just took off my airbox cover tape (had it masked till i'd get to the dyno).
With the the airbox "closed" it had a little dip @ 6800rpm but it was due to a slight too big main jet. with the airbox open it revved all the way up with no problem to 7300rpm.
When pulling the tape on the box I "lost" 1nm, but that could be due to acceleratorpump setting. The dude agreed that finetuning the acc. pump would solve that little loss.
stock 2in1steel header
I'm pretty sure the pig will gain some HP when using an aftermarket header.
