My dad dropped off his '12 DR650 for me to "freshen it up" if you will. I bought him a different type of choke (mounts on engine) as well as got him an extended fuel screw. Carb wise, everything is stock (whatever those parameters may be) as well as the exhaust. With that being the case, what is considered the optimum range of turns of the fuel screw for the stock carb? I wanted to try and play with the fuel screw some to get the sluggishness out of it before I went to the full jetting kit/airbox mod route. Thanks!
