I just looked up this thread and have a question for you all. I just installed the 103 stage IV kit and added the ACR's as recommended. When I try to start the bike the ACR's stayed engaged preventing any compression to develop which of course stops the ECM from allowing spark. Anybody have any experience with this and might be able to suggest what the problem is and how to correct it? This is one of those very infrequent times when I wish the dealer had installed the stage IV and they could solve the problem.

On my bike with the ignition on and then turning the run button on next to the start switch I can hear it click in and then back out about 8 seconds later with out starting the bike.

Where do I find the 103" stage 4 pro race kit, I can't find it on the HD web site? Anyone have the part number for this kit? How is it different from the stage II 103" kit?
Sorry guys, don't have an acessories book and did not know about these stage 3 and 4 103" kits, can anyone enlighten me.

Thanks for the replies. Smokindave, you can order the stage IV kit from HD or any internet vendor that supplies HD factory parts. It is part number 27517-08A for '08 and later touring bikes. It comes with pistons, jugs, cams, 58mm throttle body, 5.3gps injectors, 110+ heads, perfect fit pushrods, SEST, and a stronger clutch spring. You have to buy the ACR's and harness separately. You also have to buy the SEST cables and software separately. I have the part numbers for that stuff also if you need them. If you go to the MOCO web site and search around enough you can find a link to the SE catalog in PDF form and print it out. It has a lot of stuff that isn't in the SE section of the main catalog, like this kit. Here is the link to the page that lets you download it

as far as the other responses go, I did install the new wiring harness which does have a termination to the ECM, and I did reflash the ECM with a tune that has the ACR function enabled. I think either the ACR's are hanging open or a valve is hanging open. I don't hear anything closing after any length of time with the ignition switched on and there is never any compression after any length of time turning the engine over. I am going to try disconnecting the wiring to see if they close. If that doesn't work I will start looking at the valves. The 110+ heads have huge valves and required some relieving of the rocker bases and covers. I think it is possible the springs re rubbing on the edge of the rocker base. I mostly wanted someone to confirm that the ACR's are normally closed and powered open (which only makes sense, but the MOCO doesn't always do things that make sense). Thanks again for the responses and I will post an update when I have news.
