having a little issue...

have you tried jetting down till it surges and then back 2 jets?

and if so...did you also jet the secondaries down too?

how old was this motor?

when i first broke in the motor @ wyotech we did some light pulls on the dyno and it was @ 16:1 with 66's on the primaries so i rasied the primaries to a 67 not long after and just recently went up to a 68. i think the pv is to big tho @ 6.5.

the motor was built middle of 09... has like 6300 miles on it. none at the track
