So recently my 2004 Vulcan 800 has begun to stall when I release the clutch slowly into first gear. I've done a lot of digging online and I don't think its the side stand switch since the bike lurches forward then dies. I can get it to go forward if I open throttle way more than necessary, but it shudders a whole bunch when doing this and doesn't sound great. Once I get moving though the problem goes away and only seems to happen in first gear. I have already adjusted the clutch cable tension and set the idle speed to factory spec as well. My plan is to put in new spark plugs, clean my carbs, and have a look over the clutch plates to see if they need to be replaced. If y'all have any other suggestions I would appreciate it.
