hi just returned from another few runs and still stuck at 73 give or take a few tenths besides having raised my rpm by another 90 due to heads at 150 psi,j gapped plugs and indexed with e.f.i dialed in correct,
my rpm's were i think good with a low of 7240 and a high of 7280, but the average was 7250 which was seen most on my pet 2100.
have ordered a special dyna fly from carl at island as i seem to be stuck at this number no matter what i do and what mods i add..
last year after i fitted the prop i was getting 72.5 all the time without loads of mods and a lot of work so i suspect my prop is out of pitch as i was spinning these numbers at 7100 without mods added over winter although the rpm's were measured on a tiny tac so i cant quote for firm.
off out in garage in hour to remove prop and check with crude gauge i now have and suspect this is whats holding me at the same speed...
should have done it before i fitted but still learnig and more each day.
any input will be great and thanks in advance ...paul

Salty I run a 14/22 pitch on the Dynafly with your setup and the 05-06 are hitting 75 MPH with it.
