I bought an '05 from a friend last week with only 1,600 miles.  I bought it to have a spare bike around for my daughter or SO to ride, because it's really too cramped for my 6'2" frame.  I do ride it back and forth to work and around town but after 30-40 miles, I'm done.

My question is how to adjust the carburetor so the bike stops the surging feeling I get.  I can get rid of the suging by keeping the choke closed, indicating the bike is running too lean.  All my other bikes have fuel injection so I don't know how to fix this issue and don't want to invest in a performance carburetor.

Thank you,
Curt

Your air mixture screw (on the right side) has a brass plug blocking it. Take a drill and a screw and drill it in a few mm to remove it. Yeah, and then do the white spacer mod, and perhaps a more rich main jet. Go to the tech section and download the clymer repair manual I posted a while back.
