Hello,
I have a 1978 xs650 that I have been bringing back to life. I overhauled the engine with new seals and rings, cleaned and synced the carbs and she fired right up. After running perfect for 350 miles, the 10 mm nut that holds the timing advance to the rod (the one the runs through the camshaft) came loose while going 55 mph and caused havoc. As I coasted to the shoulder, there were a series of backfires.
During the event, the timing advance bracket was cracked. I replaced it with a new one (same part #) And now I'm getting alot of motor vibration. The bike seems responsive but I would be afraid to take it over 45 mph due to the excessive motor vibration. Also the points have to be ran in full advance for the rotor mark to line directly up with the F mark at 1200 rpm.
I had it running perfect and now Im at my whits end. Please help.:banghead
