Hello, did some searching and did not get any hits.   Checking to see how best to check if my electronic compression release are working correctly?  Bike is becoming hard to start getting kick back.  New battery, plugs, baker comp sprocket, and new hayden chain tensioner, but problem still remains.  Thinking maybe E-Comp releases may not be working correctly.  thanks in advance.

Have you done a compression test?

[OnUrMark]

No I haven't yet.  Thanks for the reply.. Is that the best way to test the releases? and if so, can you provide some info or link to how do this correctly?

IMO that is the best way to test the whole system.  Remove plugs and open throttle blade all the way.  Perform compression check.  Note numbers.  Pull CR fuse and repeat test.  Numbers should be different by about 30-40 psi.

[OnUrMark]

I'll give that a try.  Thank you for your input.

Anyone know which fuse controls the ACRs in a 2012 CVO?  They don't exactly have it listed in the owners manual.

I think it's a relay, do you have the CVO supplement? It's in there.

The easiest way to run a compression test with the ACR's disabled is to do it with the ignition OFF.  The way you do that is by jumping battery power from the positive lead at the starter to the solenoid.  I use that technique often enough I rigged up a simple push button remote starter switch to make it simple.  One lead has a clamp that you can hook onto the starter positive connection, and the other lead has a spade connector that connects to the solenoid.

If memory serves it's labeled as "spare" and next to the fuel pump fuse. It's been a couple years since I needed to look at one but see if you've got one that's labeled as "spare" there that actually has power going through it.

I couldn't find anything specific to the 2012 CVO fuse box, but I did run across the attached diagram for an ACR overlay kit.  As Twolane said, see if you have this setup in your fuse box, and if so see if you have power to that "spare" fuse.

Disconnect the TCA at throttle body before compression test, may throw a code, check and clear later. My 09 service supplement calls to remove the system relay to disable the acr's for testing. Should be similar for a 2012, maybe.

OnUrMark, may I suggest you get the service manual and the cvo supplement, they sure are handy. Good luck.

According to the CVO supplement,

Get engine to normal operating temperature,  remove pugs connect Compression tester, throttle held wide open, turn engine over until needle stops going up.

With ACR`s connected  130-170 PSI
With ACR`s disconnected  200-220 PSI.

Of course that's assuming  a standard engine config, if you have done changes (head work/head gasket/pistons/cams) then you will have to estimate using the above as a guide.

I have 113 with flat top pistons, 30thou head skim, 30 thou (Cometic) head gasket, Andrews 54 cams, after my rebuild was showing 180-190 with ACR`s connected.

Ride safe.
