My 2019 roadking, 124ci 22xe cam, was dyno tuned awhile back by HD. I dont want to take it back there. It runs well in most respects although I wonder if a different cam would have served me better. Maybe I will try a different one in the spring.

My problem is with the cold start. Under 50F I may get a pop and die, it could die without popping, or it could just do its usual surge then drop to warmup RPM.

I first adjusted cranking and warm up fuel upward 5% below 20C . I got a nice black cloud poof and rich smell then it died as it usually does. I know better than to change two things at once.

Im gonna toy with it but any guidance for a clean start at any temperature would be appreciated.

 

Try bumping your ve tables up in the 5,7 and 8% columns, up to maybe 1500 rpm and see if that helps.

 

Thank you. I adjusted cranking fuel upward from 20C down to -16C, by 3% and it fired amazingly. I will try a fresh cold start again in a day or so to be sure it wasn't a fluke, or was affected by my previous start attempt.
