Re: 90 Vulcan 'hick-ups In Fifth Gear Only
Just a thought... If you had the carbs off and cleaned them, then you might check and make sure you got the diaphragm back in the grooves around the edge correctly. I had my carbs off and when we put them back together, the bike tended to jump and have a flat spot while accelerating. It was the vacuum (or lack of) that was causing the problem... Don't know if this will help, but when I got that diaphragm back in the groove correctly, it was like a dream come true... the bike started accelerating smoothly through all the gears again... You might want to check.
