Ok guys. I am new to these bikes and have been steadily building my cb550. I started it today and it was going fine then all of a sudden CLANG! I killed the engine and slowly tried to kick it over. Well I kept getting a "hard spot" then it would move freely. I took off the valve cover and realized it wasn't the valves. They all look fine and dandy.
I thought that it had to be a rod at this point.
I tried to slowly kick it over again and realized that it wasn't turning. I pulled the stator and cranked it by hand. The engine turns fine, but I hear a sound from over by the kick start.
Again, I don't know these engines well. Is there an issue with the 550's and the kick starter? Its a 76.
Is it easy to fix, or should I pick up a 650 and swap engines? (one for sale locally pretty cheap) If it is fairly easy to fix, I would like to keep what I have. I am not a mechanic, but have have some skills (mostly old VW's).
