Hi all, I have been getting a slow leak on the outer right, no 4 cylinder carb for a few weeks now. Investigation has led me to find that the alloy body is cracked and it looks like I need a replacement carb body.
Does anyone have one ?
Or a complete bank and I can strip etc ?
I am in the UK and I have found a vb43 carb body, will that fit ?
Cheers

Hi Kirky, my carbs are the vb42, are the 52's a straight swap.?
If so, what sort of price are you thinking of.?
I am in the UK, so overseas shipping might be expensive if you are based Stateside.
Thanks

What model cb750 did you have them on?
It might help to try and measure the centres for cylinder head inlet side to make sure they will slide in the short inlet rubber manifolds, as well as the same for the airbix connecting rubbers too if you can.
Thanks
