Need to find cause of hard start, long warm-up and idle that drops. 97 750, jetkit, K&N open airbox, under engine exhaust. Looked at ducatisuite to find where to look for vacuum leaks and was wondering whether a mityvad could be used to synch carbs and test the fuel pump (vacuum pump-same right?). Any ideas welcome. Oh yea, new plugs, bike running rich. Jet kit only has about 8000 mi.
