Se 120r complete engine?
I understand there is two 120" motors listed in the SE catalog.
SE120R
&
JIMS120
However, my question was related to this statement:
"you realize there is a "standard" 120 on page 28 that comes with a 263 cam"
Where is the 3rd "standard" 120 on page 28 that comes with a 263, all I see are JIMS engines on page 28. The whole page 28 is dedicated to JIMS 120&131 raceing engines.
There is no third..........Jims 120 has a 263 cam......jims isnt as hot as the S.E. version and cost $2k more as I priced it today........I am told that some of the components of the S.E. version are made by Jim's...........Buddy of mine just installed a 131 in his Road Glide and its wicked fast.......
excellent points phil ;-)
A motor that flirts with 130 HP has to breath & while the FC rocks on smaller motors & even some "torque-centric" bigger motors, it just won't flow enough for something like this mystery 120R.
Better be look'n for a Boarzilla.
As far as the motor goes, I sure wouldn't be lined up for any of the 1st ones. Let someone else find the shortcomings (crank, crank bearings, cam, etc) & you'll significantly improve your chances of satisfaction....
Additionally, building a motor for some ridiculous HP "#'s" does not bode too well for what the typical Bagger Dude is after ~ TORQUE. I know that it's gonna have decent torque, but it sure looks like the focus is more on higher RPM power, than low ~ midrange.
But then, WTF do I know.....
sounds good but is that 2-1 se exhaust new? never seen it before.
Any ways they told me this 1`20R is a limited production also, that I might need to get it quick as there may not be any around come winter. Well if it ain't around I guess I'll have to go back to my old plan as I just can't come up with the $$$ till winter.
I already put my stuff up on Craigs list to see if any1 might be interested. Tell me if you think I got the stuff priced to move reasonably. http://grandrapids.craigslist.org/mcy/1880054646.html
96" 1650.00 complete air cleaner and all
Ported and polished SE 110 heads 650.00
88" jugs 85.00
exhaust 150.00
Take it all for 2100.
What ya think anything overpriced there. I need to get 2 grand out that **** to make the financial adviser (GF) interested in the 120R

First of all you know a lot.

This shouldn't be a mystery motor to you. Remember the SE 120R kit that had the cases bored wrong, that you and your buddy found? HD even put out a memo on it that I sent you? Same engine only assembled. I even thought about having your buddy assemble it, but the distance made it cost prohibitive.
I don't mind going first either. I'd rather of been part of the Apollo program and went to the moon instead of waited for technology to improve and taken a ride on the space shuttle Challenger.
Afa blowing it up, I have HD backing me on a side bet. Most people won't get a deal like that. Most builders wont give tgat deal either.
Thanks for the heads up on the exhaust. I'll order it tomorrow. Do I need a certain type baffle? What wiuld happen if I kept it restricted and quieter? Just less power?
This is all fun to me, no offense meant.
Best regards

There is 110 tq at 3000 rpm. What more do you want? What does a properly built 103 or 107 give you
Just because I'm on a Street Glide doesn't mean I'm riding coast to coast each weekend. Most of my riding is in the city.
