I've been hunting for the right part numbers for Starter Jet(SJ), Pilot Air Jet(PAJ), and Leak Jet(LJ).

This is info for those having problems with number for dealers that don't have a clue. Most of the WR/YZ are interchangable the older ones have some different P/N for air jet/pilots but from 00-04 they all seem to use the same P/N's.

The only thing I'm confused and not sure of is the Pilot Air Jet vs Main Air Jet. They don't show both air jet on the newer WR's but they seem to be the same.
I got the PAJ from Thumper FAQ for the WR250 and the MAJ from Yamaha micro fiche.Can anybody tell me if I got the right numbers for both the MAJ and PAJ's or if there is a difference.

The main air jet and pilot air jet part numbers on this list are the same part.
