I have an 02 WR426 that I'm setting up for a guy. This is where we are now: Throttle stop gone, "Q" exhaust, stock cam timing, air box lid gone. 155 main, 40 pilot, one size leaner on the needle, clip in the third position. Bike seems to run well other than a richness, blubbering when the throttle is cracked slightly, just off idle. Bike goes through a fair amount of plugs too. Will the BK mod/accelerator pump adjustment straighten this out? I have scrounged around on this site but havn't found the details on the procedure. Any help would be appreciated. This bike is ridden in the 5,000-12,000ft range.
