Hi all, I'm new to the forum, this is my first Blackbird, I have wanted one for many years and finally got round to getting one yesterday. After viewing and test riding 5 I finally picked the one I wanted, all appeared fine, the ride home was fantastic with no issues. Unfortunately this morning I went for a ride and at the second junction leaving home I went to set off, I let the clutch out and just as it was just about all the way out there was a loud "bark" noise and the bike jumped forward and nearly threw me off, it stalled and I looked stupid. I re started and set off without issue. During my 30 min ride, it happened a further 2 times. I returned home. I went out this evening, I let the bike warm up before setting off in case this was the issue but no, a little further from home this happened a further 2 times. Has anyone come across this before? I'm thinking maybe glazed friction discs or worn clutch springs?
