Ive had my 2000 road king for ab 2 months now. I bought from a close friend that I know took great care of it. About a week before I got it he replace the fuel tank and ever since it has to turn over for about 5 secs before starting and then has to run for several minutes with your hand on the throttle before it will idle with out shutting off. I thought initally it might be a little trash in line and would eventually clear out. I've run a few tanks through with no change. Ill appreciate any advice.
