Carb holder question

[Guest]

I rebuilt my carbs on my 82 650E and put them back on but gramps says the holder's and said they are in bad shape and need replaced. Here is a picture, all of them sort of look like this one. Inside looks ok to me, outside looks like you see it. What do you guys think?carb holder.jpg

Gramps is right, those need replacing. They are called intake boots, and they should be soft and easily squeezed. Keep the ones you have and compare them to the new ones when you get them, you'll understand what he's talking about. I'm not sure if your specific model also has o-rings behind those intake boots but if they do order those as well.

Cosmetically they don't look good, but it all depends on whether they leak when fitted.

If the rubber is hard, they need to be replaced.
If they fail the leak test, they need to be replaced.
If one fails then, ideally, they all need to be replaced.

You''ll need the o rings too. All part numbers here

While you're at it, check the rubbers on the other side of the carbs too. If they are hard, shrunken cracked, they'll need replacing too.
