Ultima 107" motor on a 90 model Bagger
Ok guys, now that uall have run 107-113-120-127 ultimas, which one would you suggest for my 90flhtcu. I have a built 80 in her now but the left case is cracked.instead of replacing the cases im going with a new ultima motor.I was going with the 120 because of the different stroke than the 127 and from what i had read thru ur pages the 127 is an animal.I do all 2up riding and me and the olelady weigh in about 420pounds total.Is my selection the best for me ,or should I go to the 127.

I am really impressed with this new cam and lifters even though the lift has increased from 640 to 650 and more duration, the bottom end feels stronger and smoother through the full rpm band, it used to die out at 5000-5200 but now it just keeps pulling. The valve train is much quieter and once I get the new pinion gear it will be better yet since the cam gear/Pinion mesh was a bit loose. Just as a note Ultima is using the 89 style pinion gear so when checking this make sure you use the .105 checking pins not the .108 to get the right sizing.

Ordered a 120 this morning. Going to put it on my 85 FLHTC to replace the original 80" evo with a cracked rs case. already a have Barnet clutch with SE spring. Six speed Rev Tech I put in the stock hsg a couple of years back.
Ordered a one piece brg for primary. already has single fire Dayna Ign. Had to do that some years ago because of high compression. still have stock starter. Don't know how that will work out.
Anything anyone can think of will be welcome. Engine will be here Friday. Will put it in this weekend.
Thanks for your input.
