Hello. I've got a 2011 Boulevard S40. The reason I'm posting is that it has an ongoing engine problem which I've been unable to resolve.
The engine wants to die while riding the bike. It may run fine for a period of time - anyway from a few minutes to a much a 45 minutes into a ride. After the trouble appears I have to blip the throttle to a great extent to even keep the engine running. If I don't do this it will die immediately. So that's the basic nature of the problem as it occurs while riding.
I've had it up to the Suzuki dealer, as well as a neighborhood mechanic. Both times they rebuilt the carburetor, and both time the problem came back after the motorcycle set for a period of time. (Anywhere from 2 to 4 weeks) I'm not really sure what would explain all of these symptoms, and so I'm writing in hopes that someone can give me some suggestions. Please let me know if you need me to provide any more details.
Thanks in advance for any help offered
