I have an issue with my 05 Suzuki GS 500f not starting without me clutch starting it. This issue started after I tightened the chain. For a few weeks before this, I'd had trouble starting but I could eventually get the bike to start just my turning the handle bars for a while and continuing to press the start button. Now, there is literally nothing. I figured it was the starter relay so I got a new one, but it didn't work at all. The power didn't even work so I put the old one back on. Now I can clutch start it but does anyone have any ideas about what it could be? It is possible that the carbs are so clogged that it cases clutch starting to be the only way it starts? I ask this because I used to not have to turn on the choke to start the bike but after a while it became a requirement. Also, when I get the bike started, it seems to take a lot longer before I can turn the choke off.
