2012 Road King in limp mode
My new 2012 Road King has 65 miles on it and is spending it's 4th day in the shop at the dealership. It started running rough and the engine light came on.
I did a search on this forum for such and learned how to access the trouble codes. It had the following codes: P0107, P0651, P1510, P2127, P2138.
I find that these are related to the limited performance mode, throttle position, twist grip, and MAP sensors. I realize some of the codes are flashed because of the limp mode operation.
The issue is intermittent, but I had no problem clearing the codes and replicating the problem in my home shop. It would run great, then the engine light would come on and throttle response was poor- limp mode again. I even think once it happened when I turned the handle bar.
Since it has 65 miles on it and elctrical parts can be expensive and tracing wires is time consuming, I took it to the dealer. I am confident they will find the issue.
Anybody had similar problems with 2012 RK? If so, what was it?
Thanks in advance,

My 2012 RGC had the same issue. It was a bare wire that some how got the insulation pealed on it from the factory. It was shorting out and since it happened to be one of the handlebar wires it put the bike into limp mode. Took them a few days to find and fix it, but it has been fine ever since. It is just frustrating as hell!!

Can you tell me specifically where the wire was and what color?
Dealership called, said they didn't find anything. They cleared the codes and it won't do it again for them. I'm going to pick it up and ride around town to see if it will do it again before I get very far.
Here we go...............

Pull the connection apart at the TCA ( where the carb would be ) and blow out the connection and put some dialectric grease in there. Snap it back together solidly. Look at the way those wires bend almost backwards, no wonder there is a problem with bad connections!!
