Had my rebuilt F2 Dyno'ed on a Dynapro a few months ago, It has the following spec. Rebuilt crank .5 rebore and Matika pistons Stock porting stock carbs unknown fiber reeds stock head but used one leaf of an Athena head gsk TSA mid range pipes stock Ign and pv control Kenny said pipes should peak around 10,400, so think with a programable ign and a little more advance at the top end could free up a few more horses. red lines F2 blue lines stock RGV 21 green lines piped RGV 21 anyone have a graphof a ypvs in a similar state of tune they want to share ?

His race pipes will peak at 10500. Midrange will be around 8
Looks like you have his road pipes which will peak before 10
My tsa pipes peak at 9400
Your making good power for standard porting

Oh Yeah, just checked an email from TSA "Road ones peak at 9600-10000rpm depending on setup and the race ones peak at 10400-11000rpm again depending on setup."
