Hello. My wife's 883 has had a problem since new (totally stock engine-wise) with what seems like a lean condition. When engine is cold, it stutters like mad for quite some time before the choke comes off. Once it warms it runs ok. When I pull the plugs they look to me like they are lean. I have messed with Suzuki bikes for years and have mechanical aptitude, just new to the HD way of doing things. I keep reading about stage one kits and jets kits and whatnot, would something like that help this bike? and what exactly is a stage kit, and what does it consist of? One note, she wanted it to sound less of a sewing machine and more like the big brothers we ride with, so we knocked the baffles out of the stock pipes. Sounds good, but the problem still remains, and wasn't affected by this change.
