yesterday, my '92 vulcan 750 began running on 1 cylinder, much like the problem mentioned here by several other people- but mine idles fine with both cyl's while in neutral, or if i put it in gear with the clutch held in & rev up the rpms. the front cyl cuts out as soon as i start moving. if i really give it LOTS of throttle, the 'bad' cyl will fire a little bit, sporadically(just enough to make for a slow, very jerky ride). this is all unaffected by rpms, gear, or speed. i have also noticed white smoke in the exhaust from the right(front) tailpipe, & there is a small amount of oil seeping from around the flange where the exhaust pipe enters the front cylinder-head. im broke, with a 9-mo daughtr, & have to use this bike to get to work! somebody please help, i have no idea what to do!!!
