Carb rubbers question

(1/3) > >>

Peterplank:
Hello all, I have removed my carbs from 500K1 to clean out and replace float valves & seats after as they are overflowing.
Question is.. the inlet rubbers are very hard and stuck and I reckon they need replacing as I can't see they will go back on as so stiff.. are the pattern ones ok or oem best / better ? Are they fexible when new and is there a best re installation order with rubbers / carbs / airbox side ?
Thanks for any help with this.. as I'm sure you know it's all very tight in there. :o)

I would go for the OEM rubbers,

Fit to the bank of carbs, use some rubber grease on the alloy inlet ports,

And wriggle the whole assembly together,

It's your choice. In the pic the 4 new OEM boots I have bought at the dealer decades ago. The rack has been of twice, since I have bought these, but so far I have not felt the need to replace the old ones. Why? Simple: I had no indication whatsoever there was any leaking. So I decided to leave them alone. They still don't leak. This is my policy always. Now if you're deep in the engine doing an overhaul, it's another thing and ofcourse it's best then to replace all rubber parts.
For the rest, I am always amazed to learn how long things live, if you simply leave them where they are. But I have to admit, many will not agree with me. I have lots of parts still waiting in their plastic bags.

Peterplank:
Is it possible to install bank of carbs then wiggle in air filter rubbers ?
Just trying to figure best way of putting all back in without mashing everything..
:o)

Johnwebley:
Awaiting answers with interest


PS,I have never done it
