Went through valve clearance check yesterday and discovered an interesting anomoly. Valves were OK at 9227 miles but on start-up after check got a very slow idle, CELP symbol and code 33 with analyzer tool. Yours truly had muffed reconnecting spark plug so the cap was just sitting there. Slow idle was about 1300 rpm, handle bar tips and mirrors vibrating noticably and very much out of character. Found the loose cap, reseated, cleared code with tool and all back to normal. Target rpm was 1750 according to the analyzer data and the bike was doing exactly that. Code 33 is faulty injector. Code 37 is faulty ignition coil. Go figure.
