WR400 Accelerator Pump

2 posts in this topic

Will the 1999 WR400 idle without the accelerator pump? My APs rod and linkage are missing, and the bike will not idle. (Idle is turned all the way up, jets are clean). When coming to a stop, if I pull the clutch in without giving gas it will die immediately.

The apump will not affect the idle in any way.

Idle is a function of the pilot jet circuite

Put in a NEW pilot jet, a NEW fuel screw oring, and adjust 1.5 turns out before starting.
