My buddy just bought a like new 2007 CVO Road King with 1,500 miles. It's pretty much stock and has the original Screaming Eagle pipes and air cleaner on it. Does this engine come from the factory with a high flow SE/AC? Can the stock pipes handle the higher exhaust flow? The first thing that I did to my '07 RKC was replace the air cleaner, pipes and add a PCIII. Do you need to do the same for the CVO engine as far as heat abatement is concerned?

 

First post here. Hi all. The answer is yes, the CVO bikes are set up with the proper ECM's to deal with the added heat of the performance parts added.

 

The 110 engines do come with higher air flow systems. However, they still come from the factory running very lean. If you were to install free flow exhaust you would also need to do something about a fuel management system. I took my 2007 FXSTSSE to a dyno tuner and used the SERT. By doing this you are able to set different throttle settings to different fuel ratios. For example, I have 13.7/1 at idle and top end throttle. As I reach cruising speed I lean out to 14.1/1 for better mileage. I went from 89 to 95 horses by doing this. Unlike the 96s you could get as high as 18 horse out of them by doing the same thing, including a high flow AC. I have another 09 110 I just bought. I have some top end noise issues with it which I will post about later. I am going to ask if there is a stage one down load for the 110s and will let you know later. Just remember heat is the enemy and ultimately will be the death of the air-cooled engine.

 

Well, my buddies CVO Road King has Vance & Hines Ovals on it and not the Screaming Eagle pipes like I wrote above. I guess he needs to get the PCIII before he burns the SOB up.
