Just got back from Yamaha dealer picked up some parts long drive away and got 4 donut gasket sleds all tore apart and the new donut gaskets will not fit over the manifold piece at all seem way to small is there a difference in 06 and 2011?? Part number on package is 99999-03989 did they just give me wrong ones??

 

[WinderFab]

Yes they gave you the wrong ones.
I’m pretty sure 06-10 apex are 35mm I.d and 11-18 apex are 38mm I.d

 

[happy1426]

I gave them this part number to order 8HG-14623-00-00 is that the right number for 11 n up

 

[WinderFab]

Yes that’s the right part number.. do you have a way of measuring the id of the donuts they gave you?

Yes they gave you the wrong ones.
I’m pretty sure 06-10 apex are 35mm I.d and 11-18 apex are 38mm I.d

Yes

 

[WinderFab]

Should be 38mm or a hair under 1.5 inches..

 

[happy1426]

Ya it’s just a bit under 1-1/2 the new ones and old ones are almost dead on 1 1/2”

 

[WinderFab]

So then they should work
