PC v Ypsh pipe testing

[kgbg]

I just got done tuning on a customers 450R. He had the Yosh Ti pipe installed when it got here.
I did not build this bike, just tuned it in. I have built many with very similar, if not equal mods and this one was off the pace a bit.
The customer requested that I run it with a PUlseCharger installed.
I did so with a standard length PulseCharger, race core, and no torq tube.
I was pleased to see the power come back.
I jetted and tuned the bike for the Yosh, and only threw on the PC, no jetting. The main was rich with the PC, so it would have yeilded a bit more on peak numbers, but look a the advantage down low, and in the rideable range.

Here it is.
Good job John, your pipe STILL rocks!
