Greetings form Jonesborough, TN. I recently purchased a 2009 CVO Road Glide in Electric Orange. I love it. I am currently looking at engine upgrades. I currently ride a 2008 Road King Classic with a custom built 124" engine. I'm looking to have some fun with the CVO and looking to build a 113 build. Thoughts? Ideas? I have read many threads on here and looking for as much power without breaking the bank. I broke the bank with the custom 124" build. I would like to get close without goin over. So, i feel the crank should be Darkhorse crank as suggested by Prodrag. I wanna travel on this bike and looking for 130/130+ if possible without the cost of machining the cases.

The 2009 CVO currently has Woods 777 cams and shes powerful, for what she is. But i'm always in search for more power. Since I'm looking for more compression, the pistons should be addressed. if I'm upgrading the pistomns, I should go ahead and increase the bore to a 113". The lower end should be addressed also wirh a Darkhorse Crank and Timken Bearing. I will require the 58mm throttle body. I have a set of gear drives for the cams, so I'm currently looking at the Tman 590 or the 625 cams. Suggestions would be appreciated.

Depending on what you mean about “traveling” I think if you built a 113 and achieved those numbers on a dyno it would not be a very smooth touring bike.
My 113” evo has not quite the hp/tq you are shooting for and I’ve ridden that bike everywhere. It’s a little high strung for touring IMO.
My current 124 M8 CVO barge (900 lbs) is a little higher on those numbers you quoted and is a VERY nice touring rig. It IS designed for higher torque and is very smooth. 70K miles on that one at this point.
I would suggest being realistic about numbers and go with your plans on a nice 113 set up for touring. A comfortable, easy to ride torque motor is way more fun than higher revving, HP motor.
You can reach out to some of the engine builders on here and chat with them about how you ride, how much weight you have , budget, etc.

JMHO, of course…..good luck and welcome to the forum.

HD Street Performance:
1.1hp/cu in is about the line for a twin cam when special care and feeding starts, in my experience. The 113 can be a very nice motor combination based on a CVO 110 starting engine. All the usual items to get there. A timken is not needed. I would suggest just crank trued, pinned, welded, balanced, and H-beam rods. Or just buy an S&S crank, plug and play. This is all about a motor combination and not to forget the pipe and tune. If you have a good shop that can provide the services they can help you based on previous similar builds and suggest parts combinations. I get calls all the time trying to "pick my brain" especially for cam choices. I am out of that business. Picking bits and pieces out of the context of the whole is bound to fail or just be mediocre at best.
