Jim Libonati at Mega-Flo did all the machine work and porting. 124", 11.3:1, S&S Superstocks, HPI 62mm cable tb, 6.8 inj, T-Man 662-2 cams (not ps or ps 2), dragula 1 exhaust with 3" baffle, AIM vpc and Evo Basket. 3.04 final gearing and a sticky 180 rear tire.

Confused in the charts you show an 07 FLHX 124" with 150/150 HP/TQ 3.04 final gearing and in the signature 07 Street Bob (FLHX?) with 174/141 HP?TQ with 3.07 final gearing. Two different bikes or builds?

On another note as you may know the answer. I have a lesser build 116/116 HP/TQ (EPA compliant cam & tuning) with a 3.15 final drive ratio. It should by simple gearing calculation run out in top gear at 6,200 rpms at 150 mph. It easily pulls 6,200 in 5th 120/122 mph and pulls hard to 5,800 or 140 in 6th then abruptly stop accelerating. Is it possibly torque short at that rpm (to overcome drag) or likely something else? This is an M8 with speedo disabled by switch to avert the speed limiter. Speed shown by gps.

 

Street Bob and street glide, 2 completely different builds. My other sheet is on here too. Have you talked with your tuner about your issue??

 

No. I was just looking at my dyno sheet and noticing that is where my torque really starts to drop off.
