I have installed several 107" Ultima engines in baggers with great results. The 107 is the perfect touring engine & is easy starting without the compression releases, nice idle, runs cool, NO oil blowby, good mileage, does not require a monster clutch & is not as exhaust sensitive as the larger engines. There are no drawbacks to running the 107 & it will put a BIG smile on your face.
You will need a single fire coil, a HD clutch spring or extra plate clutch, Good slip on mufflers or 2 into 1 & an air filter adapter if you want to run a stock style air filter with the Mikuni 45. These engine are a great bang for the buck & very reliable. Good luck with your build & ride safe.

GTC Cycles,
Thanks for the reply. I am in the process of changing the motors out. Just got the 80" off last night. will try to install the 107" tonight. When u say HD clutch, I assume you mean a heavy duty clutch spring plate? Do you have any numbers of the diapham clutch spring you use or is it easier to just put another friction plate in? I have ordered a single fire ignition, oil filter mount and an oil cooler, hopefully arriving by the end of the week. Again, thanks for any info.
js124,
thanks for the offer, but i have already recieved the 107". it shouldn't be hard to sell though.

GTC Cycles,
Have you had any issues with ignition timing on these motors. On another forum i use I was cautioned about timing.

"Be extremely cautious with the breakin do it like midwest says, also be sure you setup the timing on the motor per the spec's of midwest.
They have had problems with some pistons to cyl clearance that was made worse by poor installation.
If any doubt get someone to help that knows how to setup the ignition. It should be right out of the box but you need to be sure." Storm4U,Where are you finding reviews for these or any motors. I called myself searching everything and everywhere before i bought this motor. Asking on several forums about these motors. Since buying I am hearing some negative feedback. Thanks

There has been problems with the timing issues on the ultima motors . I have seen the damage first had . It required replacement of the rear cyclinder and piston . I know Ultima ships them now with the timing set . I don't think you can even adjust it . I don't own one but have had a friend or two who have .

I'm not saying anything is wrong with it . Put it in and run it . You have a waranty to cover you . I think they took care of the problem now . Just don't try to tamper with the factory timing .

Hey fellas,
Got everything done, straight by the book. However, It wouldn't crank on the first try. Ran the battery down trying. It popped and spit a couple times but never fired off. Checked the timing, did not change anything, just looked where it was set. Getting gas and the coil is firing the plugs, so I must have flooded it or i never got enough gas to fire it . Charging the battery until I get home from work tomorrow and try it again. Anyone with any suggestions ?
What about it Goat? Did you have any problems getting your 113" to start on the first start up ?

Make sure your battery is fully charged ! They don't like to fire with a week battery . I would keep the charger on the battery or a set of jumper cables on it while trying to start it just to give a little extra . Make sure you put it through the proper heat cycles . Let me know how it turnes out .

The Goat,
I hooked up the VOES also. Charger has been hooked up all night and should have the battery hot when I get home from work.
Thanks

Hey all,
All is well. My dumba$$ had the coil wires reversed so the back was fireing when the front was supposed to and the front when the back was suppose to. Changed the wires and she came to life putting a big smile on an old mans face. Done a couple heat cycles so far . Should get a couple more tonight. Thanks everyone for the support and help.

Sounds like you are good to go ! Now get that thing broken in so you can feel the power . For the first little bit ride it where it feels the smoothest . Make sure not to lug it . Best of all have fun !

Hey Goat,
This sumbitcah runs like a raped ape, and I ain't got it over 3500 rpms yet! I was thinking maybe I could/would have myself a sleeper, but when I light this bi**h off everybody at the stealership looked up. One fellow thought it was a small block chevy with a race cam in it. How can I say..." I Like IT" without being too obvious. I will hit the 500 mile mark in a couple days, after that I will probably have to order a couple back tires!
My question to you is , do you have any idea what the oil pressure on you bike is ? On this old dresser the guage only goes to 40 psi. Running at 3000 rpm it is showing over that , warmed up and at idle it @ 35 psi. I know the gage is old and gages aren't accurate for sh*t, but my 80" showed only 20 lbs cold and maybe 10 running down the road, hardly anything at idle. I have checked all the oil lines, none are crimpled and have got return. Just wondering if I should be concerned. Another question is the top end noise. This motor has a little more valve train noise than the 80" but I assume that is nomal.
Any insight will greatly appreciated.
later.............

What all did you change to make it work? It sounds like something I would like to do with our old '90 Ultra.

PaJoe,
All I did was to take the 80" off, set this 107" in the frame,bolt it back up. I had to buy a oil cooler, a single fire ignition, two new plugs, a oil filter bracket and some oil line/hose. I have also bought a se clutch spring, but have not installed it yet.
Let me know if i can help...

dog155,
Thats great ! I don't know what happen with my S&S113". When it had the .520 cam I didn't notice the oil, but I put a .600 lift cam and all hell broke loose. Motor run like hell, but when I would stop there would be oil everywhere. I put a canister to catch the oil under the frame as suggested on another forum, I called S&S. I did everything but take the engine apart and check to see if the rings might have lined up. I sold the bike to a friend and it was still blowing oil when he hit a car a couple months ago. I almost bought the bike from the insurance company just to take the top end down, but they thought a lot more of it than I did. I am not saying all of them blow oil, but there are a lot that do. I use to stay on the S&S tech site trying to figure out what to do. It might have just been that motor. and then again this 107 may start it later on. I had 12000 miles on the S&S when I sold it.
later..........

Hey thanks Goat,
I loaded the pictures backwards to photobucket and I can't line them in sequence for some reason. But, you get the picture. I am no computer operator nor a mc mechanic. Both skills elude me.
Its time to change my oil and let her rip.

Hey all,
Coming up on 1000 miles on the Ultima, all seems well at this point. Starts easy, idles good, runs like a bat out of hell, no oil blow by yet, no smoke. I was concerned with the rideablity of the larger displacement motor, but as noted, several of you have been running larger motors than this one on baggers for years with no problems. If nothing comes apart or flys off or explodes in the next year I will be a happy camper.
Again thanks for all the support. Goat how ya doing ? Your 113" doing what you wanted it to? If this 107 ran any faster or got there any quicker I would probably hurt myself ! Too much motor for an old man like myself ! I love it.....
