CB400F Carb overhaul

(1/10) > >>

Lobo:
Gents,

About to tear down the carbs & overhaul. Before I start I note a couple of small plastic 'tie rods' tying the 1/2 & 3/4 lifters together. They're both cracked / broken.

What is their job? - the bike seemed to run fine, and any tips for re fabricating them - will light aluminium sheet do or will that be too stiff?

Ta muchly,....

sweetpeauk:
They should be thin stainless, will check thickness later. Mr cooper should be able to help you source a pair.

Lobo:
Thanks SweetPeaUk,

But... what is their purpose?  And secondly, I'd have to say the (broken) pair I have look original - are they aftermarket perhaps? 

And finally, if thin stainless, or plastic as mine were, do they need to be flexible?

Cheers,
Lobo

sweetpeauk:
I think they are for keeping the lifting mechanisms parallel to each other, the theaded end and locknut above adjust the synchronisation so they hold the lifter's so they can't float. They don't help in the lifting of the slides. 

sweetpeauk:
Thickness is 0.32mm, so going to be fiddly to make. I have three sets of carbs and they all use the same material.
