What is the name of this part?

I believe it is called the needle daiphragm for the carb, but im not entirely sure. Started my rebuild today and noticed all the rubber boots had holes in them. Anyone who knows that its called would be much appreciated

Yamaha calls it Diaphragm assembly. North of $100/ea. from Yamaha.

 

I sell them after market for a bit less than that. You can get a set of 4 replacement rubbers from Sirius Consolidated for about $100.

Guessing you meant to enclose picture, but it is probably main diagphragm.

 

If there are any holes, they are junk. Even pinholes.

 

Not cheap. There is an ebay seller that has a set much cheaper. One of the guys here replaced mine on the slides for me when I bought set ion ebay.

 

They are $87.57 each from partshark.com
