Misfire and popping on startup cause - maybe
about 4-5 thousand miles back, my '17 AT manual started popping and misfiring a bit on startup, but then would straighten out after being ridden just a short distance. Worse when cold.
Working on her 32K valve check, found one of the spark plug caps had developed a crack in the rubber and the screw that makes contact with the spark plug wire had corroded off, so some arcing must have been going on.
Only 32 bucks for a new one.. (:> Oh well.... Changing spark plugs as well, man, are THEY buried...
So if you have similar behavior... might be the reason...
