I was having trouble with my RKC running funny and flashing the check engine light. The bike showed it had stored codes 11 and 12. I did a little research in the EVO forum and found your post above after doing a search on codes. I too had a less than tight battery connection. As soon as I tightened them up my bike ran better at startup. The idle was more steady and consistent. That should take care of the problem.

I was thinking I was going to have to do a bunch of work to find out what the problem was, buy one of those break out boxes, etc. and throw money at it. Saved me a ton of time and money. You got a tall, cold beer on me if I ever run into you.

 

Thanks Carl, I know what you mean you don't know where to start looking and it turns out to be something so simple. Have a good Christmas.

 

Battery terminals are common to work themselves loose. Not a bad idea to check the battery whenever normal maintenance is being performed.

 

Glad to see you found the problem. I have a `97 RK with FI and had the same problem awhile back.Tightened up the cables and no more problem.This has happened to me a few times so I always ck.the cables about once a month.I think bike vibration is intense in that area.Skip C

 

Good to hear, a simple fix. The 95-96 has to have a scanner, 97-98 ecm was updated to OBD1 onboard diagnostics and flash codes. The 3 key on/off brings up codes on my 97 RK.

Robzuc97, impressive information but I think it is for the Delphi OBD2 system, far superior than the M&M.

Merry Christmas to all, I made a Christmas day ride last year in 30 degree Ohio weather but this year my heads are off, what a shame, it warmed up to the 40's.
