JD Jetting Modified Float Bowl with Leak Jet

Replacement float bowl with leak jet installed. Replaces non leak jet float bowls used in KTM 400, 450, 525, 560, and 625 models from 2003 to present; Yamaha YZ426/450 2000 thru 2004 and Yamaha WR400/426 2000 thru 2002.

The leak jet float bowl meters fuel from the accelerator pump more precisely for less low speed sputter, stalling, and bogging. Works particularly well for high elevation riding and low speed rough conditions.
