A friend wants me to hop his bike a bit. 2012 Street glide 103" with a Harley Super Tuner. Two questions:  1' I've been told that the S&S 110" cylinders have wider fins and look funny with stock Harley Heads. Any comments?.....2, At a static compression of the stated 10.5:1 the Andrews 57 would have corrected compression of 9.74:1 and a cranking pressure of 205. Is that a little high? It would be given a good tune.
But what do I know? I drive a party bus.

SnS 110 cylinders are thicker. The SE 110 cylinders are same as stock. Verify deck height then calculate static comp, that cam has been used many times at 205ccp.

I never noticed that before.

Thanks.

Thanks a LOT   :hyst:

Just for that, go look at the right saddlebag on your Rushmore (and maybe later) bagger. There is what looks like a run in the paint on the right bag, rear panel, about 2/3 up on the left. It's actually a flaw from the mold that got painted over.

Once you see it you can see it from across the street . So THERE  :hyst:

:slap: you made me go down stairs in my pj's and check that out.
Spent an hour looking all over the Shark for that run  :nix:
Then I realized you are talking about those Rushmores....
I'm going  :scoot: when my toes warm up!

Just used a 110"/57/our HMM Stage II Heads combo, in a Voyager Trike kit for a local client.(4 wheeler)
He opted for a Cobra 2/1 pipe.
Large torque off the bottom/mid....almost 130.

Built two of the Harley 110 cylinder  kits this spring wtih flat tops and 57 cams with zero issues using 85 cc chambers. Great torque and SOTP riding was awesome. Cranking pressure of 205 should not be a problem at all if you have a decent tuner around.
If you don't have a sense of humor you probably have no sense at all.
