With Patrick Racing HC Pistons (10.25:1), Titanium Rods, HD dual valve springs, newest cams, ceramic lifters, YAMAHA SpeedStar ECU, Custom VBAK filter setup(Thanx Churchkey), V&H Propipe, Custom Mapped PC3, SpeedStar clutch, 1 tooth down front pulley, The 280 rear meat which rides on an 18" instead of the stock 17", 92 Octane gas on a 72 degree day at 900 feet. She made 93.15 HP and 109.79 ft lbs.
This was a huge improvement over stock with the 280 tire, I got a best of 72.7 and 97.9 before installing the PR parts.
There was no head work done and the valves are the stock size. The heads were scrubbed clean of carbon before reassembly. There is a ton more potential with 2MM oversize valves and some good headwork.
Swapping from the 240 to the 280 ate 9.47% of the HP and tourque across the board. This was verified on the DYNO. The loss from the stock 200 on the 17" rim would have shown even bigger But I didn't bother getting it done. I'm guessing about 14-15% total loss.
The bike in its best normally aspirated form is capable of speeds in the mid 140's by GPS. Iv'e never had mine over 131 MPH by GPS. Remember this thing is a cruiser there is no way to get out of the wind, hook your toes under the brake and the shifter, hold on for dare life and hope to god a BEE or June bug does not get in your way...
I never bothered with the 1/4 mile stuff.
