Miles on your 107" big bore kits.
ultra, i did the 106. im $2500 in parts WITH the CRs & heads worked. after reading so many posts with dyno numbers, im satisfield with my numbers. im pulling similar tq numbers as guys with 120rs and 117s.
too many people get on here and debate the heads, cams, who should do the work, etc, blah blah bullshit. you'll be happy with it...i pull wheelies, smoke stock dynas, and have beat my roomate's Ninja 600 in stoplight drags

Thats an amazing improvement for $2500. Did you do the work yourself? Which kit did you use?

16,000 miles on my FM 107-'09 RG. It's always run hot, but warmed up quite a bit with the thinner cylinders. I also had some starting issues after the engine heat soaked at fuel stops. (kickback/grinding) Installed the SE compensator which took care of the vast majority of the problem and then the addition of some of Jason's fans (Wards Parts Werks fcs fans) the took care of the rest. Other than these few problems it's been trouble free.

Update: Another year and a total of 11,000 miles on my FM107 and still runs flawlessly. Still the best money I've spent on my 2010 Ultra. While not necessary, I did add the AIM clutch and compression releases this year.

I've been following this also, as I too am interested in motor upgrades.
So far all the replies except 1 or 2, have put 1 season's worth of miles (or less) on their bikes. In my books, reliable motor upgrades should be trouble free for > 80K miles or I might as well leave it alone.
Anyone out there with some real mileage on their 107's that would deem it to be a reliable bore size?

Thank you for the replies. Been sitting on the fence for awhile now and I think I'm gonna take a ride over to Little Chute this spring. I think I'll pass on the heads and just go for the extra cubes and a good tune.
