I'm looking for some help with a poorly running SSR 110. Bike is brand new and starts up with one or two kicks. As soon as you put it in gear and let out the clutch it coughs and sputters until you pull on the clutch. My guess is it is running rich because the plug is black. I'm looking for some sort of spec for float height. I can't imagine it would need to be jetted, because it's fresh out of the crate. Has any one else had this experience with SSRs?
