I'm getting a lot of low-end bog and stalling - especially after bike gets good and hot. Bike idles well, starts well but stalls a lot in slow, technical stuff. Seems to occur when I roll on the throttle as you might do when crossing a large rock or log. According to the manual, I should tune the pilot circuit so I plan on adjusting the fuel screw. Bike runs great from 1/4 throttle on up. Just need to get the low end dialed. Any ideas are much appreciated! BTW, I ride mostly between 1000 - 3000 ft elevation.
