113" in build stage and curious as to service life.
Seems to be a big difference experienced generally and from what I have read, everyone takes care of their machine. So my question is... why do some of these give miles of trouble free service and others shit themselves in a relatively short period, is it:
1. Occurs on certain engines
2. Quality control at production
3. Differences in factory vs independent builder
4. Different parts

Opinions?

I'm gonna get Crucified for this.

Many (not all) people who have had the problems with these engines, May have been responsible for the problems.

2 things in particular. Too lean and timing too far advanced.

Again Not all can be explained away that easy. But most probably can.

I'm probably gunna get it as well...
Ok.... lets assume that it is operator inflicted of a factory built/tested engine, whom has just spent the good part of 4-7K on his engine, built with loving care his pride and joy. Is now going to fill her with cheap oil, even synthetic, kick it in the pants and ignore break-in procedures. Surely this thing isn't going to fail prior to the break-in period ending - or is it. Longevity will be questionable, but for the most part the failures I read occur in the early stages.
Brad you can probably shed some light here. Is it not standard practice for the factory to test run these engines up, even to full power prior to shipping. Something we are then told not to do until the time frame required to bed the rings in.
Are these engines that delicate and "on the edge", so to speak.

i usually buy unassembled components. sometimes i sell motors that are complete...usually black ones that i cant buy unassembled. honestly i dont know who preruns motors. harley does. accurate engineering does. i dont believe s&s does. and i dont think merch does, i could be wrong. maybe ultima does, they didnt used too.

thats a doosy of a question. i wonder about 6000 mile recomendations....i wanna hear about bottom ends at 75,000/85,000 miles and ring replacement at 40,000/50,000 etc.

Yeah likewise and as it seems with the failure rates and sighs of relief that ones chosen motor has made it past 6000 mi.
I guess finding that holy grail of bottoms ends will be all but mythical. Let me know when you do so we can enshrine the thing

motors last, i've gotten that kind of mileage out of some severe strokers that were put thru the ringer more times than i can count, i just dont know if ultima has been around long enough to hear those types of stories, or if folks arent trying or whatever.

I cant speak for all the problems ultima is having, however operator error was definatly not the problem here. The timing was set exactly to their specs. I never took that motor over 2500 r's. Pistons started slaping after a couple hundered miles.WTF
Lets say the timing was off one degree, that is gonna cause the engine to fail. That is just wrong. I am nowhere near an expert on motors but somthing doesnt sound right here.
I didnt even mention how f...up their customer service is, sending the wrong pistons......twice. they didnt compensate my builder for all the rebuilds. didnt even compensate me for the price diffrence between a 113 and 127.
I am just speaking to my experience here but I wouldnt give these guys a penny of my money.

My opinion on this... First, let me say that I have zero first hand knowledge of ultima engines. I have never owned one or even ridden a bike with one. When I was deciding on engine choice for my build I spent quite a bit of time. The bike I was comming off of started out as a 1999 883 sportster which built up with buell T-storm heads, wiseco reverse dome pistons and an Aerocharger turbo (Very quick scooter)... I looked into Ultima, Mid-USA 114 powerhouse, S&S, and even the crazy TURBO-ORCA motors from RB Racing. I decided at the time that S&S was the way to go for me. I bought an S&S crate 124" with the IST ignition pre-installed. This gave me a 2 year warrenty and plenty of get up and go. Bike was completed in may of 2005. I now have just under 11,000 miles and the only thing I have done to the motor is adjust the pushrods. She hase taken me from Buffalo, NY to laconia, NH, to Daytona, FL, and to Myrtle Beach, SC. While in FL I ran her on Speed's performace's Dyno and she made 135.8HP and 142.5 FT-LBS of torque. With the mixed results peole seem to be having with the Ultima stuff, I would seriously consider an S&S. In the overall cost of your build what is the real impact on the $1500.00 or so premium? What is the warrenty worth to you? Just food for thought...

I am not an expert on motors. From all of my past reading there are a lot and I mean a lot of people that are very happy with there Ultima motors...........and there is always a couple people who are not happy or have had some serious problems. My thoughts are that not every engine manufacture is gonna build a motor and not have some failures..........especially when you have all of these newer builders out there working on these motors (myself included) who dont have the experience of someone who has been building bikes for along time. In this thread alone there is a bunch of people who are really happy and there are some who have had problems.........this seems to be the case most times I personally read about these motors.
