Carb Dust Boots

Hi All,

I bought 4 carb dust boots from DSS to replace my missing & split ones but I can't see how they go on.

Their made of really thin rubber that looks like it tears easily and the hole is way too small to fit over the carb end.
It looks like I have to dismantle the whole carb linkage and re-sync everything, correct?

Given how expensive they are I would rather not mess them up!

haynes66:
i dont know either, but good forum name dude!

flatfour:
I fitted some to my CB750 a few years ago and, as the carburettors were already off for reconditioning it was an easy job. I don't think that they could be fitted without removal from the lifting bar assembly though.

Arch stanton:
Apply a little rubber grease. Then they just slide on.
They are stronger than they look.

They do not go over the carb ends but should slip into the grove on the circular disc that is part of the throttle body lifting mechanism.

You just have to remove each carb from the manifold to separate the forked end of the lifting arm slide the boot over the forked end and then reattached the carb to the manifold and you should not have disturbed any settings that require re-syncing. Getting the boot into the groove and keeping it there can be a bit of a pain though.
