AP Rebuild

1 post in this topic

hey everyone, ive been doing some work on the 99 WR400, and when i was riding it earlier i noticed that the bike was bogging a bit off the line so i went to clean my carb and when i opened the AP i noticed that the diaphragm was quite rusted and looked really rough, and like it wasnt doing its job. so i decided that im going to rebuild the AP. i was wondering if someone could tell me which one of these diaphragm's should i order? - http://www.cheapcycleparts.com/products/634949-yamaha-5jg-14940-17-00-hard-parts-diaphragm-assy?comment=AP http://www.cheapcycleparts.com/products/681670-yamaha-5jg-14940-18-00-hard-parts-diaphragm-assy?comment=STD http://www.cheapcycleparts.com/products/681671-yamaha-5jg-14940-19-00-hard-parts-diaphragm-assy?comment=AP . also since im replacing the diaphragm should i get a new spring while im at it? and is there anything else i need or should replace? thanks, -Wes
