The intake valve tightened up a bit.......Adjust the valves, checked the
timing, changed the oil, cleaned and gaped the plug, (it was a nice gray
color), cleaned the carb and even adjusted the brakes...All fixed she is
purring again..One angel blue C70 back on the road..
Wish the British bikes were fixed this easy..:-)
Cheers,
Eric
