I have a 08 Ultra and for the past few weeks, when I start the bike cold there is no problem. If I stop for gas (10 min or so) and go to start it sounds like a loud chunk in the starter. I thought I chewed up some teeth for sure. Checked the primary, no metal shavings. I have been looking at other blogs and some say it is the starter cluch, some say its the jacking gear. Looking for some help. Anybody else had a problem?
