Or is it there to stay?
My bike runs good except when I snap the throttle open real quick the bike will stall.
Does anyone have any sugestions?
99 WR400, airbox lid removed, throttle stop trimmed, WB Pro Meg & tapered head pipe w/9 disks, YZ timing, DVP needle #4 clip, 178 main jet, 50 pilot jet, pilot screw 1 3/4 turns out.

p.s. I tried a search but most of the old post "could not be found."

I think the 50 pilot jet is too rich, back off this to a 48 and then make adjustments to pilot screw.

What about the acc. pump? Does anyone know what the ideal setting is if you have the adjustable carb. Thanks for all the great jetting input. Mickey
