On the Fuel Moto website, they have a ton of Dyno charts. Most have whatever combination the bike had before the 107 upgrade, then you'll see the after results. Depending on your exhaust combination, you could see some huge gains over Stock. There are even a few Stock 103 Rushmore's for comparison.

Here is the link to their dyno charts page..

Note: If your bike is complete stock, do yourself a favor before you start buying exhaust, AC and a tuning kit. Call the guys at Fuel Moto and have them give you some recommendations on what combinations work the best with their kits and still meet the sound your looking for. They are by far the experts in my opinion.

I will warn you, looking at these charts could be dangerous. You will get the fever Hope that helps...

 

I have the FM 107 w/o heads, and with the addition of cams and Jamie's excellent tune am extremely satisfied (doesn't mean I'm not entertaining the notion of a 117"). I bumped mine from a 96" which offers 11 more cubes. Power difference was quite noticeable and appreciated. However, in your case you're already pulling with a 103". Much more cost effective to take her to FM, have them drop in cams of your choice and a fine tune. Guaranteed to put a smile on your face, yet still offer a powerful, dependable work horse. And I assure you FM does top notch work!

 

Well just cams and the push rods lifters etc was $750 107 lot is $1,300. For $500 more so I would just go with the 107 kit. And do the install myself. Went through the vids last bight and install seems simple.

 

I just installed the FM 107 with 777 cams without head work on my 103. Big difference in power. Can't speak for the difference felt on the Rushmore 103's.

 

I want to go with the FM 107 kit and level B head work, but the turn around is 5 weeks on the head and cylinder work, the other option is to get a set of the shelf, since I have a 2014 SGS with low mileage ideally I would want my own stuff back rather than doing the swap, any thoughts on this?

 

First off Thanks for Your service. call Jimmie at FM and see whats up!! Maybe wait til winter for tear down and install??

 

I will call Jimmie tomorrow, I will probably wait since our summers in WA are very short anyway if the wait is too long, thanks.

 

CANT WAIT.... Advantage to living in Cheeseland! Dropping off cylinders on Monday and if he can't get them done in the next week or two, I'll use a set of theirs. Mine has about 80K so guessing whatever I get back will be as good or better. Going with the 555 cams and no head work. Will be significant from my 96 in the ole 2008 ultra!!! Tear down starts tonight.

Hey brother I'm playing catch up myself. I should've started with this one for sure though. Maybe then I would've had the money for headwork LOL. I'll have a thousand miles on it this wknd. Time to twist on it and see what she's got!!!!
