Default CVO Upgrades?

Are there any useful gains to be had from additional work to a CVO? I've already got the programmer, pipes and air cleaner. I was wondering about cams or other performance accessories. This is on the 110 or 114 that I'm curious about.

There is a section in the Parts Catalog that shows the performance options / Stage kits, for each engine. Harley also produces graphs to show what to expect. Of course you can go with other non-Harley options in which case they will have to tell you what to expect.

The more you hop up your engine, less reliable its going to be in my experience. More power, more heat and wear and tear.

I for one like the 117" Big Bore kits for the 110" motors. (Aftermarket or Screamin' Eagle)

BUT........ I also had extensive crank work, SE Timken Bearing, newest SE Comp Sprocket, Heads ported, Larger TB/INJ, Aftermarket Cams & Lifters, new internal engine parts throughout the motor, 2-1 Performance exhaust and some Dyno time.

Not cheap, but Bigger Motor, Better Performance, More Reliable, Less Heat and Much, Much More Fun!

did s&s 585 cams,valve springs lifters,pushrods in my 13' 110. Along with tuner and exhaust it makes 110hp/122tq vs the 85hp stock. No need for bigbore imo. You can head work,throttle body and cams and be in 130hp range easy AND still be plenty reliable.

Sure are.

A 110 with head pipe, mufflers and tune is about 96 HP and 114 Torque.

I built a 110 to 123 HP and 124 Torque. Much more fun. This is not HD parts other than the Cylinders. Custom CP pistons on this at 11.4 compression.

Then I built my 13 CVO King to a 117, and I am at 138.5 HP and 140 Torque. WAY more fun. Power everywhere. Runs much better than stock

So who built your tune for that then? I could see doing that build in my shop, but would need tuning.

My self and a good friend built the motor, Don at HD street performance did the heads. Brandon at JB Performance did the tune using a TTS tuner.

My friend and I carefully match parts such as Throttle body, intake, Injectors, cams and compression and head work for what we were looking to achieve out of the motor. I want torque early in the RPM and a long flat curve. This bike is a blast to ride, because there is lots of torque from 2500 RPM to red line.

The 110" engine is a sleeping giant, and they respond readily to performance upgrades.
Boring to a 110" to 113", with the proper head/cam combo. is a very cost-effective way to achieve very good power.
