Just sent to us by customer that very happy. 2017 CVO with Stage IV SE kit. SE cam replaced with TTS 200 cam.

 

That looks real good Steve!! Any idea on what the heads are? Stock? CNC? Exhaust? I want to show this sheet to the guy I was doing the quote for.

 

That is one nice curve. The AFR is unbelievable.... Nice job... Who was the tuner?

The Bike is just a 117 Stage IV HD kit. The cam was not used and replaced with a TTS 200. Going from memory a Stage IV kit is the larger bore cylinders, 11:1 pistons, SE8-515 cam, CNC heads, 5.5 injectors and 64mm throttlebody. You can check the SE catalog to make sure I did not forget something. I do not know what exhaust was used but can ask.

Tuner is Jason from Perfect Performance in MN.

 

thanks Steve. I was thinking this was your 117 kit for the 107. I didn't realize it was the HD 117 kit for the CVO. my guy is still on decided on what he wants to do for heads

 

That is what all Stage 4 charts should look like. Sad that the Mothership can't seem to get there.

 

Actually the MOCO can make that power easily...just not with the emissions strangulation that creates excessive combustion temps created from increased cylinder pressure. This condition is prevalent in hot climates so the bike needs to be carefully tuned (fuel and timing) to avoid the dreaded detonation that all-too-regularly shows up on air-cooled emissions regulated vehicles.

I call Bull!

My straight from the factory car makes as much Hp/CI with a much better torque curve than a Stage 4 117" CVO. It is not rocket surgery, if Chevy can do it why can't HD?

 

Not sure you are comparing equal technologies to one another.
Chevy and others with liquid cooling, have a bit wider birth when it comes to performance upgrading.
We have to keep in mind our air-cooled temperatures are not closely held to specific ranges of operation as with LC engines.
That, coupled with the constraints the MOCO has held for tradition purposes also limits their performance capabilities.
Don’t try to compare a state of the art auto to our traditional glorified air-compressor.

I hear what you are saying, but I am pretty sure that Harley says my bike is "Twin Cooled", not air cooled.

That is their description, not mine.
