I found some good posts on step by step instructions for the BK Mod but have a question regarding the jetting. My bike has the throttle stop removed, BD baffle, and airbox baffle removed. Stock Jetting. I think my mixture is a bit lean due to the semi-opened exhaust and intake so I was thinking about moving the needle up one position. My question about the BK is, Will one position up be enough/too much or will I need to go up 2 since I think the BK also leans out the mixture? I ride in western Michigan at 610 feet above sea level. Any advise would be appreciated. I don't have any other jets than what came with the bike. Current symptoms are "jerkyness" at 1/4-1/3 throttle. Everything else is fine, starts, etc. My ultimate goal is to clean up the jerkyness for when I am cruising on the road.
