Yamaha 5RU143680100 Diaphragm Assembly

Perfect fit for my Yamaha Majesty YP400. This fixed the low power/ bad idle situation caused by a torn diaphragm. Watch the YouTube video on how to swap it out. You CAN do it! There are a few body pieces to remove to get to the throttle body but it isn’t too bad. Just take photos as you go and make sure to create little labeled screw piles so you put it all back together as factory.

This part did the trick for getting my Yamaha Majesty up and running like new!
