My stock 80" in my 91 FXR isnt cutting it anymore. Just doesn't have enough balls. Im looking to get some more out of it, however its a '91 and i believe thats the early weaker cases.

Im basically just considering multiple options and looking for some input from those who have built evos.
I ride this bike hard and push it in the mountain roads. I rev it pretty good considering. Hot rodding around town happens. We all do it. 3-400+ mile cruises and trips are not uncommon either. So basically all ends of the spectrum....i need a good reliable motor that puts out plenty of power.

-Doing a simple jug, piston, cam, head etc. swap is fine, but i can only go so big and theres the issue with my cases when i get to the boring aspect of things. What options do i have? parts and configurations youve used? Branch, Mackie, S&S, Axtell, etc etc? Stick with the 88"- 96" range? I need a good solid motor that i can push hard. Any suggestions on good tried and true parts combos?

Complete S&S engines are out of my price range. I simply dont have it. Out of curiosity I looked into El Bruto series Ultimas. For half the price of a S&S I can have a 107"-127" Ultima at my door ready to bolt in with 115-140 hp. But are they worth it?
- Does anybody have any experiences with their new motors? I know they had some issues in the earlier days but from what i can tell now thats a thing of the past and theyre cranking out some reliable powerhouses for relatively cheap.


Any input would be appreciated.

I've never owned or known anyone who owned an Ultima. I'm still terrified of them, for some reason, though.

One thing I do know: Never buy Revtech.

80" evo with cam, decent carb and good pipes should put out about 80 ftlbs of torque and 70 - 75hp

If are doing 3-400 mile day trips this has got more than enough power to do this

have done the above to my evo glide 16 years ago and have hardly put a spanner near it since

 

[tyszko]

s&s all the way

Wood w8 cam with about 10.8-1 compression and some decent head work

I've sold a couple of Ultimas. One of them was 100" to an "older" guy who used it in a road bike. The other was a 113" to a kid that put it in a wide tired chopper. The only trouble that either one of them had was the kid over reved his, floated and bent a couple of valves. I looked everything over pretty close while I had the top end off and it looked pretty nice inside. It could have used some lighter valves though. They were tuliped with a solid head, lots of weight.

I had a friend that built a stroker using his early 90's cases. The cases cracked right inside the lifter block (if I remember correctly).

I have had three of the Ultimas, 100", 107" and 127". They were all either older than 2006, or as in the case with the 107:, I built it out of a 2004 100". I say older, since in 2006 they started going with all, or close to it, their own parts. Older motors were JIMs and Maule etc and seemed stronger internally.

I don't know that I would recommend the new ones, but we have done two customer bikes with them since, and there have been no issues so far. They do run a little hot when it is 100 degrees and humid, but so do I.

Personally, if you could replace the lower end bearing I would do the S&S 89" stroker.

I built my 89, 80" evo, cam, head work, pistons, etc... at 150 thousand miles, it broke just like Larry said, right behind the lifter blocks. I was going to have it welded up but am thinking i'm gona replace the bottom end with a delcron.
Also have a 113" ultma, got it in a basketcase flt. Put it in the bagger and it ran like a striped assed ape. As best as anyone can guess, the checkball stuck and it sumped out all of the oil, scorching the rear cylinder and piston. With a 4" bore and 4 1/2" stroke, 120 poneys, imo this is a hell of a motor.

lol, Ya 120 poneys aint nothin to sneeze at!

I need a good solid motor that i can push hard...

... 115-140 hp.

It's called a "sport bike".

I just looked into these motors...same as you see everywhere, some guys put shit loads of miles on them with no problems, some guys have holed pistons.
They're made in the US. They're almost cheap.

What's the catch?

Complete S&S engines are out of my price range. I simply dont have it. Out of curiosity I looked into El Bruto series Ultimas. For half the price of a S&S I can have a 107"-127" Ultima at my door ready to bolt in with 115-140 hp. But are they worth it?

Sometimes you get what you pay for.

 

[gretsch58]

Have you looked into a Jims Engine?

 

[rockett]

Sounds like you need an R1. Or, if you want to be comfy, an FJR1300.

this is what you need

 

[rockett]

Yeah. I love my sporties, but I wish I had an FXR, too. =)

Increase compression, cam, carb etc. and the bike will rock, but if you pound it, and of course you will, because what would be the point, the left side will eventually fail. I have a collection of right-sides.

I am running a 99 Evo Softail. The engine is stock except for a andrews ev 23 cam, s&s shorty e and cycle shack 1 piece muffler pipes. It runs strong for a stock compression 80 in motor. If you want to get a little more, oomph bump up the compression (stay below 10-1 for a street motor on pump gas) by milling the heads or new pistons and run a ev 27 cam. I do 1 long tour every year and gas quality varies, thats why I stayed with stock compression. Also on a rubber mount evo a Race Brace is a must have even on a stock motor! It basically ties the engine and trans together on the right side and keeps the trans mount from breaking and keeps the powertrain from twisting. It will improve handling as well.
