I have a 2009 100" and had less than 2000 miles on it when the rear cylinder started blowing oil. the top ring on the piston had broke off and scratched the walls, but ultima paid for all repairs and shipping both ways and said the problem was a faulty ignition system so thee motor was preigniteing and they reset it and sent it back now the only problem is the noisy lifters. Just can't seem to quiet them down. I was told to remove the 600 lift cam and put in a smaller one as the big cam was made for short runs not long highway runs and the big cam is beating up my valve train. Anybody got any output on this?

The 100" is a EVO built by ULTIMA and it's the worst investment i ever made as now i have an american made motor with japanese specs as it sounds like an old corn binder.
I put in a smaller stroke cam and lost all my take off power but can run faster for long distance but need to turn the radio up real loud to hear it over engine noise.

I have about 25000 on my 127, it has always had bad lifter noise but since I put in the S&S 640 cam and S&S lifters it's much quieter. Aside from the noise it runs great, no oil leaks, no oil mist. Starts idles and runs like a stock motor but when you crack the throttle its a good idea to hang on tight. Before this I was running a 110 S&S motor which I had a lot more trouble with than I ever did with the Ultima motor, even a year after the Ultima motor was off warranty they helped me out with out any problems. Can't say that for S&S they just told me I was on my own and good luck. Besides I can buy 3 ultimas for the price paid for the S&S.

I have just over 4K on my 113", once I adjusted the valves correctly and the tuned the carb, it roars and oh yea, horsepower makes noise. I got a good solid 200K miles on the origional 80", and didnt really have to many problems except for the crappy fuel injection system. Most folks don't do their own work and/or can't afford a good mechanic. If you want a 'Harley EVO', well go spend the money. Instead, why not look into learning how to do your own work, it would be cheaper!!

I have a 127 Ultima in my 96 Dyna. The engine is the best runnung V-Twin I have ever owned! Starts great, runs very smooth, quiet, and tons of *****!!!! 125 rwhp 130 fpt. With Cycle Shack slash cut drags. Still hoping to get a 2 into 1 on it, and see what kind of improvments it makes.
Like was said, HANG ON! Power off idle, with stump pulling midrange. I am knocking on wood, but, so far, so good.

I changed out the 45mm mikuni for a 51mm screaming eagle CV carb, put on the RB Racing 2/1 Black hole pipe (2" primary's) and a 640 S&S cam and lifters. With the higher ratio rockers in the ultima the S&S cam gives 665 lift (calculated) but 650 when measured. The springs are good to .700 lift. It pulled good before but after these changes it really woke up. Once my buddy gets his Dyno dialed in then I will see what it really puts out. I used an RB racing A/F ratio meter to dial in the carb, that really makes it simple. I ended up putting in the S&S clutch as my Pro clutch didn't cut it. I found the S&S clutch really works better in every way.

That post does make a little bit of sense, but "if" your going to learn how to work on your own it would be cheaper to stay with the original Harley Evo to begin with wouldn't it? I find myself liking the reliability of the Evos lately. I can't see dropping $3600 on a motor and thinking that you have a race ready motor. I can't see anyone buying a Harley to go fast either though.
There is a noticeable difference in the torque when you go to a big inch engine. To get similar torque and horsepower gains out of a stock Harley evo would lessen the reliability of that engine. Having 100+ ft pounds of torque at lower rpms makes it much nicer riding, especially if you haul some weight. Things like passing cars and going up hills is just a matter of twisting the throttle. Even if you don't intend to "race" I am sure the additional torque is well worth the $3600 to many who have purchased the big inch Ultima engines.

My brother in law built up his 2006 Deuce to 95". Which was a total of $10,000 this was with the pipe and new fuel injection. I paid $3800 for my drop in 127" and can still sell my old motor. You work out the math.
