Low Speed Bog
Posted February 09, 2001 - 02:16 PM
This is my first ride on the bike. I added a fuel filter that slid into the fuel line hence it had a slightly smaller opening than the stock fuel line. I also installed a YZ throttle stop and routed the carb vent lines up near the airbox. Could any of these mods. cause the low speed bog or is it just the pilot screw. I did read on the YZ fourm that this is a common problem w/the YZs. Most owners have just learned to roll on the throttle smoothly at lower speeds instead of snaping it.

Do not go out past 3 turns. At 3 turns get a bigger pilot jet (45) and do the same process starting at 1 turn.
My WR400 was set at 3 1/2 turns with a #42 pilot by the previous owner.
