CB400F Carb overhaul

[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,....

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

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.

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

dont think steve has any left i want,nt 6 off him he only had 2 but you can get new ones from germany ebay

[Lobo]

Thanks guys. Will try ebay... and in the meantime try fabricating a pair from feeler gauges or suchlike - will have to look around 'my office' for suitable scrap.

I need a coupld of these too. I had one previously home made one which looked like o bit of bucycle tyre  . I'm happy to search German eBay but what are they called?

Cheers

....yup, I trawled German ebay & had no luck. As for what they may be called in German ...aye carrumba & good luck to ya! I've learned new names for bike parts that I'd have thought illegal if you shouted them on the streets....

Seriously, if you come across a (spare) pair pls let me know...will do the same.

[Lynx]

Will do. In the mean time, it might be a bit of bean can . Must be better than tyre!

[Lobo]

 ... alrighty, recon I've bought myself 20 or so attempts to get it right...!
