2005 STARTING ISSUE

[Guido]

2005. choke on, starts, revs high, stalls. When I try over and over and get it to start, idle and Rev with choke on, take it out of choke, stalls. Two weeks ago bike started ran good, not great, but ran. Need some ideas for solutions. Thanks

Possible air leak? Cracks / possible loose boots between the carbs and cylinders? It almost sounds to me like you may have had a small air leak, but then maybe something opened up and it's gotten a lot worse.

Stock air filter in place? I suspect a carb cleaning is in your future.
