Had my 107" kit installed in March, still have stock heads. Dyno said 103/122 after the build and it has a little over 10,000 miles since the build, 4,000 of them were in the brutal week of heat Fourth of July week, road temps pegged the gauge at 120 in the fairing. Would I do it again? Hell yeah! Would I do the heads? Thinking about it this winter, jury is still out on that one. I want to, but damn it runs good, how much more do I need? Ya, I know .......... I should make my appointment now, damn addiction! Oh yeah, I consistently get 40 -44 on the road, I can run it hard and get down to about 37.

 

I have 5000 miles on my FM107 this year. It runs perfectly with absolutely perfect manners. It's got the TW-555 cam in it and no head work. I average 41 mpg when I am out on the road and my cruise set at 70-ish mph.

I've posted my dyno graph from when FM did the install and tune. 106 hp / 121tq.


I would absolutely do the FM107 kit again. It works so well and the FM customer service is fabulous.

Good luck.

 

I have 10,000+ miles on mine(107). I have no issues, I ride hard,2-up,solo,city,highway. I have no anything but pure power and a blast to ride. Fuel mileage...when I get low on gas I fill it up! No heat issues. The only regret is not doing the build sooner!

 

i think I get 42-45mpg on my stock 96, stage 1 intake/exhaust, dynotuned pcv.. so 40 wouldn't be losing much, but if it drops down to the low 30's, that's a big excessive..hell my car gets 37mpg highway, and it's 8 years old..

 

I have a little over 8000 on mine, did it all in my garage its tuned with a PCV and a Fuel Moto map that seems spot on. Fuel mileage is mid upper 40's with a high of 49.7, I recently took a trip into southern Colorado to check out the fall colors, which were fantastic!! On this trip the bike went from 2500ft to 12000ft and got better fuel mileage than my buddys 2012 ultra limited and performed again flawlessly. My build is a Fuel Moto 107 with the 555 cams on a 2008 electra glide. Rest assured that after this build motor work will be the first mod not the last on my next bike!!!

 

over 6,000 miles since May--without a problem. Loving it! Get around 40 mpg--no head work. numbers are 105/120.

 

just out of curiousity..did you guys turn over your old jugs to FM? i've been in contact with them and they said that without giving them my old jugs, there's a $299 charge

 

Yes I returned then for the $299 core charge, if you really want a set of standard cylinders search craigslist and ebay they are alot cheaper than 300$.

 

i dont really want a set of standard ones, i just didn't realize that i would have to ship them mine.. i thought they'd **** me a set of 107" cylinders and that was part of the $1299

 

6500 on mine this year and still kickin ***!!!
