check colour of plug after a good flat out run ( plug chop ) should be chocolate brown and not black ?
beedspeed state a 106 -110 main jet for 166 kit and sports pipe .

Hi
I would say your main jet is way to big, I run a P2 with a scorpion and a 118 main jet. I tried a 120 and it was overfueling . Goes like a bullet with a 118 tops out at about 68MPH.
