Gsx750 carb build

[Guest]

These have been in storage for probably 12 months and are now out for a rebuild.

Plans are to replace the bolts with stainless Allen key ones. The body internals are spotless as I cleaned them not long before I out them into storage going to paint strip the outside 2 carbs to get them spotless and leave them in bare alloy.

Clean but still needs some cosmetic touch ups

Will this effect the performance of the carbs? Its on all of them. I can'tsee light through the tear but iI don'tlike the look of it.IMAG0168.jpg

is it split? looks like a mark. if it isn't split it wont affect the vacuum

the rubber has worn through on one side each diaphragm has 4 wear marks on it.

Now take the fuel bowls and the diaphragm covers and polish them out.

I can polish the fuel bowls but the top covers are plastic

So when you say "worn through" does that mean there is a hole? If there is a hole you can probably get new diaphragms from JBM industries.

I don't know if these are replaceable or not. They have a plastic ring on the top and a metal ring underneath.

They can be replaced quite easily, you have to breaker one of the plastic rings off. The is a tutorial on the JBM site on how to do it. I replaced them on a honda shadow and they worked great. Very high quality parts.

Found a Hole in 2 Diaphragms. Will need to get a set from JBM.


Carbs are spotless inside but the outsides are still abit grubby. Not sure if i should blast them or just boil them in carb cleaner again.

KFC you replace 2 you might as well replace them all. If you have 2 that ate bad I bet the others aren't far behind and for another 40 bucks you might as well get 4

Carbs are ready for re-assembly, apart from the rubber diaphragms which i will order from JBM Industries. Just need to check the float levels and either paint the 2 carb supporting brackets or replate them, I'm thinking paint.
