Just disassembled my Commando engine and thought I'd share same info/pics just in case if someone finds it interesting. Been riding with it two summers now and decided to go back to 360degrees with the crank. First of all it was not me who build this engine in the first place, so I was not aware what to find inside. I'm pretty happy what I did find. JS2 cam with BSA lifters for one. I did know about needle bearings with the cam and "vessel" underneath the cam to keep it oiled. Pistons are modified gixxer 81mm. Rods I'm not sure what they are, but they look solid.
The reason I want 360 crank is because, since I'm not racing, I want to make this bike more driveable on the street. On open roads this setup was really nice but obviously the shakes were quite disturbing on lower revs in the city (< 3500 rpm). 270 flywheel weight was 8.44 lb. I have flywheel that I think is the original, weight 11 lb.
