Ultima 127 problem
I don`t know about now,but in`02 S&S only had 2 engine builders.I`d think it`s the same still.All these assembled motors in all these catalogs and in cookie-cutter choppers are kits assembled elsewhere.The parts lack nothing and it all depends on who builds them.I had mine built to my specs by S&S because all the catalogs offer different configurations that vary in one way or another with no options to deviate.I know,it`s hard to believe,but that`s what she told me and if one starts it he finishes it.Mine took something like 4-5 months to get.It`s everything I wanted and nothing I didn`t and I`m very pleased.I only have 16,000 on it so far.Other issues and lack of funds since this depression hit have hindered my ability to tackle things as they occur,leaving it sit from time to time.
I've been working on Harly's for over 40 years and remember when all the after-market engine builders started. They all had teething problems, some of them even went out of business. They all had similar replacement problems as Ultima. In actuallity Ultima has had far fewer problems than most. When you outsource something the suppliers send you samples and you decide which ones you will use. Sometimes you get something different than what you evaluated. A part may be made of a lesser material than you evaluated and you wouldn't know until you had a significant number of failures.
Improper run-ins can also cause failures along with "owner adjustments". We've been using temp sensing dots on our engines to check if an engine was overheated or not, as that can also lead to premature failures.
All I am trying to say is that Ultima in my opinion is trying to supply quality parts at reasonable prices. How may people are riding large displacement engines out there taht would not be doing so if not for Ultima.

If anyone I knew even thought about getting an Ultima motor I'd hit them upside their head.
veeeeeeerrry interesting.
The advice I have been given is anything over 100" will not last 100,000 miles.
So that means a rebuild every 5 years- that's not too bad, of course you may not want to stray too far from home the last year or 2
I know people that tear down S&S motors to balance and blueprint before they will run them even on the street, mostly clearance issues, which is going to be an issue on any "mass" produced motor.
So if your doing that anyway, why pay S&S $6k rather than Ultima $4k for a base motor ?
The 6 speed I have is for overdrive 6th =x.86
to maintain 80-85 mph,fully loaded - uphill - against the wind - etc you need torque. Hence cu in.
I don't jump start or over rev(often) but I like to cruise @ 2500 RPM's and 80 mph.
AND get good gas mileage. Presently my bagger has a 95" with cams and 6 speed @ 80 MPH I am getting 30mpg more often less.
I think I am due 40+mpg on a motorcycle - am I wrong ???
So I need big inch

Nice read and learned a bit too. I guess as I get older (whopping 38), I have lost the interest to mod out my daily drivers. I have a completely stock 96 FLHT and after reading this it will most likely stay that way other then radio and seat. I came from a VRod that I never hardly cracked over 3k rpm. This thing runs 70 all day and has a nice pur to it. I ride everyday its not snowing or raining too regaurdless of outside temps. Its kinda like my 95 crew F350 7.3 turbo, 4x4. People keep asking me if I am going to hotrod and lift it. I just laugh since it has 188k flawless miles and still runs and drives like new. If your gonna play, at some point you gotta pay. I would be pretty hot though though if I got anything less then 20k out of a 4k motor unless I was hard on it. Great info though guys. I love this sight.
Is anyone riding big inch motors because of Ultima? There are alot of broke down big inch Ultima's on here. We just took a very low milage Ultima to the shop this afternoon for yet another issue, and it has been one issue after another since day one.

That's interesting. We have seen around HDF that some builders strip and rebuild Ultimas or other brands of engine. Roughly how many hours do you put into a rebuild and do you replace any of the supplied parts?
Then we will do the heat cycles and take it out for a ride to help seat the rings before we turn it over to the customer. Remember when a customer wants engine work or a bigger engine it's not just to go out and putt around. There are customers that feel that they should be able to ride it like they stole it 24-7. That's why we do what we do. It may cost a little now but we save a lot later both in cash and reputation.
Maybe if Ultima sold engines as boxes of parts it would help their reputation.It sounds like a teardown and careful inspection,maybe an upgrade or two can make for a 1/2 decent motor...if the eye can tell a bad part.I`d certainly be mic`n out the whole thing.IMO,an engine company should be selling a bolt-in motor or just be a parts company.That`s how S&S started out.It was many decades before they billed themselves as a seller of complete assembled engines.
Normally we pull the cylinders and cam. The short block will stay together unless we feel it needs to come apart. This usually takes about 6 hours to teardown, inspect and reassemble. We've foubd all kinds of things over the years like too much piston clearance, a ring missing (yep that's right!!) to wrist pin circlips not installed right. Usually we buy it unassembled if possible. If we find a part that is suspect we will replace it and send the suspect part back. By doing this we can feel secure about any warranty and it helps the supplier by letting him know that some of the parts he is receiving may be out of spec.

When I had my S&S 107 installed my man did the first 50 miles himself, so that sounds like 'good practice' for any new motor. We are planning a 2,500 mile round trip to Poland on it in May!
Thanks John, that gives us a better idea of what it takes to turn an Ultima into a goer! You mention 'over the years'. Have they improved noticeably of late? Is there any reason for a potential buyer to be more optimistic about Ultima today than when they first came on the scene?

One of the biggest problem we have found with any engine is improper break in and of course no customer admits to that. The average customer want to try out the engine and causes damage. That's why we do the heat cycles and uaually put the first 50+ miles on the bike and change the oil before giving it back to the customer. Another thing that we are really fussy about is cylinder finish. If you are interseted in learning about cylinder finish I would reccomend that you contact Brush Research Manufacturing at www.brushresearch.com or www.flex-hone.com and ask for their literature on cylinder finish. By following their reccomendations we improved cylinder sealing which improved torque, horsepower, leakdown, and oil consumption. Well I could go on and on about cylinder finish, but I will save that for another post. Hope this helps.
