You are going to need some clutch up grade with any 117 or 124.

I would spend the 400 on helmet quality personally. Snell?

This one has been a pain. Found a front o2 sensor code. Had a bad plug a week ago and changed it. Maybe sooted up. Iíll check tonite.

Case boring version allows 117" with stock stroke :)

If I'm after low end Bagger torque, would a SE255 be a good candidate for a 117?

Wouldn't a 117 benefit from 110 heads, as opposed to my stock 103 heads?

All things being equal (same cam profile), which kit would have better street manners and less heat, the 110 or 117?

Thanks
110 heads with the HD drop on 110 kit ends up ~9.5:1, good left side power and more tolerant of a load of bad gas with the 255s. 
Having the cases bored for the "CVO" 110 KIT now, allows for a drop on 117 kit if you want more later.
If you're going to do this once, and keep it forever, I suggest case bore for S&S or Axtell 117" kit, and then use CVO heads and pistons cut to match the compression choice.

I like the sound of these two choices. Would the 117's street manners be equal to those of a 110? Or would the 117 have a choppy idle, buck at less than 2K RPM, have increased heat, etc?

If I bored the cases to accept a 117" kit, do you recommend using S&S, Axtell, etc. over HD 117" pistons & jugs? If so, why?

The bike in question presently has ~40K well-maintained miles (disclaimer: crank run out was never checked when 255's were installed, using stock lifters, at 1K miles). How long can I typically expect go before I have to start thinking about a rebuild of some sort?

Thanks, once more.

Drop on 110 kit works well, but that's the limit, displacement wise, until you split the cases.
Stock 103 heads with the S&S drop on 110 kit yields ~10.6:1 to 10.75:1 compression, too much for the SE255 IMO. 
Stock 103 heads with the HD 110 drop on kit ends up ~ 10.3:1, still high for the CVO 255 cams.
If you use the 110 heads, then compression drops to ~ 9.7:1 with the S&S kit, OK with a spot on tune.

I think a lot of people overlook their gearing.. I know my bike was way overgeared for EPA reasons..
The 30T pulley helped a lot..

I put a 30T front pulley on my 2007 FXSTC (stock was 32T).

Nice bump in torque, but not the direction I want to go with the 2011 103" Street Glide we're discussing. I'm happy with the stock gearing for that bike.

Thanks

If you are happy with the RPM range you're in I would have the heads done and a "good tune". That would give you the best bang for your buck.

My 103 with Stock heads, stock 46mm TB, Andrews 48 cams, .030 head gaskets gets me 95/114. Tuned with Powevision by a very good tuner.

I like the RPM range of my 103" w/255's. It's just that every HD I have now seems slow since I started riding Ducatis, lol.

Did you add the .030 head gasket? If so, what does that get you, more compression?

Excuse my ignorance, but what thickness head gasket do I have on my stock 2011 103"?

Thanks

I do know the rod small ends have a reduced width compared to the other full rod ends of the 3/8 and 5/8 stroke cranks fwiw

I lost weight now everything is loose fitting, including helmets. I'm thinking of this one. Anyone try it yet, or is it too new?
