Alright ill start with the background, I have a fatboy year 2006 carbureted. I have been working on it last winter as I have posted pics of my sled few times. The problem started with regulator as I have JL hd 600 amp installed with 2 6x9, I guess this set up was putting high stress on charging system therefore which I figures out it to be faulty regulator which I have changed and its charging 14.3 to 14.5v now . It rode good for about week or so but now it doest even run for 20min and it stalls. I guess when its hot that’s when it stalls. Another issues is when it shuts down there is no power to the starter. Lights were ON but no power to starter and after about 5 to 10 min power back on starter and first crank will get it running and this will go on with hiccups and backfire in between the runs. I have already replaced the circuit breaker and starter relay. Please any input will be helpful......

please response so that i dont have to take it to stelership and save some bucks......
