Guys, one of my buddies who ordered a FLXHSE2 told me he is thinking of waiting for 2012 models since they will probably come with 120 CI engines?!! Did anyone hear about that? I heard HD is already selling SE 120 CI engines....

[mlb3164]

Yes they are selling them as a race only item not for street use. Doesn't mean you can't install one since I have one in my 2010 FLHX. Don't expect the super high TQ and HP numbers advertised. Does make a huge improvement over the 96 engine I took out.

[Rogzy]

Thanks man.
Here in Egypt the dealer sells them as street legal. My idea is since they introduced the 103ci on some touring bikes, it would make sense if next year they introduced CVO with 120ci engines.

What kind of numbers are you getting?

[mlb3164]

I am getting 120HP and 123TQ on a conservative dyno. Not bad but there are many 103 and 107 getting the same or better.

Other than motor change what mod's were done, breather, pipes etc?

[Rogzy]

So what u're saying is that with engine mods I can get higher output from the 110 CI engine? I heard about the 255 cams and 58 mm throttle body. Anything else to suggest?

If you replicate the parameters used for the advertised numbers - same throttle body, same exhaust, same tune - you will get the advertised numbers.  I know a couple who have achieved it....

Absolutely not.  The heads (untouched) on the crate 120 are far superior to the heads on the 110.  Out of the box, the 120 produces great numbers.  Now if the 120 MVA heads were further ported, cams, good exhaust, throttle body - I suspect the 120 would push or exceed 140/140 numbers.

If I had one of those 120 motors that's what I'd be doing.

Motors don't have a thing to do with playing with Maude.

Why is that?

Let me explain so this doesn't sound like a slam of Sadunbar. Not my intention.
Those MVA heads work quite well on the 120r motor. That does not assure they would produce equally well or even decent on a 103-110" motor with 4.375 stroke with a peak rpm that we seem to see as about 5,500 rpm. My comment is based on what the motor demands and each motor, each intake tract, has to be considered for it's physical characteristics and the application. This is not a slam on the parts either they have their place and would be right at home on a 124 or 131 motor as well. I just wished they would have used bronze guides. Notice the cam that is supplied with the 120r. The timing is a little non-traditional but IMO that is purposeful as well to suit these heads and motor configuration. The dyno I provided is proof that just some blueprinting can further wake these up.

Do the SE120R's have the crank runout issues of the rest of the HD line up?

[PierceEye]

I have not heard of crank run outs on the 2010 counterbalanced motor???
I am pulling right at 102hp and 124lb of torque at 3600rpm hp tops out at about 5300rpm but the torque drops down to about 105lbs but I can pass just about anything as long as I am in the powerband
