My '94 500 is a lot older, but I think the '07 still has a Keinin CV carburetor so it might be the same thing. It wasn't working when I bought it, so I rebuilt the carbs and it was bogging badly, as well as taking forever to start. Sent it off to carbjoy dot com to get rebuilt properly, and was told:
- it was missing the starter plunger springs (that's for the "choke")
- the carbs "were pretty clean but it is possible your idle/slow circuit (connected) had complete or partial blockage"
$300 later (plus a few weeks wait while parts got back-ordered from Japan) it works like a charm. If your choke slides out and in really easily you've probably got the first problem - mine was like that, and now it's a pain in the ass to pull it out and push it back.
