It's a shame all of the FM dyno charts are missing. They have done a lot of research that could really up the value of this thread. Any chance of getting those graphs back?

I think Fuel Moto is working on a searchable database of charts - query by displacement, cam, exhaust, etc. My guess is its a few months out.
It's all about air flow, and the weakest link in the chain is what will limit you.
When I had my FM 2007 EGC 107" build done with Level B heads, Fuel Moto suggested going with the SE 50MM with 49MM injectors, which they found did a good job matched for the 107/heads build. Rinehart true duals should provide plenty of flow. You'll realize another 10/10 or more I'll bet.
oldhippie, had my throttle body replaced like I said I would, and get better injectors 6.2 grams, and a 55mm 1.7.0 throttle body, from HPI, man what a difference it made in performance, now I'm saving money to get it dynoed, it throws me back into the backrest, I can't believe the difference in performance, I just can't say enough, thank you!
2015 RGS Stage 1 Tune
Steve had made two Maps, I picked the lesser of the two, there was only a drop of a few Foot pounds of torque from 105 down to 102. But taking some timing out for this Texas heat seem to be the smart move. The base line numbers was 77HP and 96TQ, the difference in how the bike runs is night and day. Hats off to GMR Performance

I'm glad that worked out for you. Enjoy the power!
I'll bet you're getting decent mileage too.

Readers ... when comparing dyno charts, always watch the correction factors. This posting is STD vs. SAE.
Not taking away from the posters success, but as an example, my numbers are 115/124 SAE and 119/127 STD ... quite a difference when comparing curves from other bikes.
