Ap diaphragm for 2004 250x

Recommended Posts

The accelerator pump diaphragm on my 2004 250x has disintegrated after 9 years of use. I have been looking online for a replacement part and it appears that Honda only sells the cover, diaphragm, and o/drings. Also, I found that Honda now supplies an updated AP kit, cover, rod, o/drings, diaphragm. I was looking for some advise, should I make the effort to do the upgrade kit? If so, does it require any tuning, ie. leak jets, timing adjustment, AP mod removal, etc.? You see I have limited time and just want to get the bike back together and running well as it was before the diaphragm broke.

Lastly, does anyone know of an aftermarket supplier of just the diaphragm?

Turns out Honda only sells a complete kit; pushrod, oring, dring, diaphragm, spring & cover. Part 16021-KRN-671. Direct replacement. I replaced the diaphragm, oring, dring & spring from the kit. I never found information on the upgrade kit and the dealer had not heard of it. Possibly the upgrade kit was for a later year. Bike runs great now.
