I spent a couple hours today tuning, and I ended up with these settings: -168 main -48 pilot -stock needle in 3rd clip from bottom (1 richer than stock) -pilot screw at 1 turn out -pump delay just misses the slide -accel pump squirt @ .5 secs -STOCK exhaust (anyone that can out ride the stocker better be getting paid!) Of course, I am in south texas, basically sea level, and about 65f today. The throttle response is much better and it pulls very strongly, but I still get a bog off the bottom if I completely and VERY quickly open the throttle all the way from idle speeds. I am hitting VP tomorrow to track test it, I spent 20 minutes running up and down a dirt road today, stopping to play with the pilot screw, trying to eliminate all the bog...but it seems a natural thing for a big bore stroker to have some bog if you completely open the throttle at low rpm? Anyway, I was just trying to get some input on what other riders in this area are running as far as jetting on 2000 models with the BK mod.
