Carb tune pro dead or carbs issue?

[Gsxr_rory]

I've got a gsxr srad 600. Carbs were totally rebuilt last year. Bike starts and runs yet when the carb tune pro is connected there's literally nothing no reading at all?

I've checked double checked and triple checked and cannot for the life of me find out why.

If you turn the carb tune pro upside down you do get a little reading bit nothing worth writing home about.

Any ideas?

I take it this is carb balancing gear? You're only measuring vacuum pressure so...

There is no pressure Well, none to measure so that would hint at a blockage somewhere in the chain. Either the port on the carbs, the pipes or... the gauges are knackered All of 'em?! I'm assuming there's four?

Simple tests for almost any equipment: try it on another bike or borrow kit to test on your bike and see which of the two is "at fault."

This is a Morgan Carbtune yeah?

Have you tried sucking on the pipes to create your very own vacuum?

Hi,

Yes this is a Morgan carb tune pro.

I haven't tried sucking up give it a go and see what happens!

Try opening the taps on the gauges vacuum pipes...

So today I refitted the carb tune pro. I tried it without the restricted in and the bars did move but barely. With them fitted it doesn't even register.

I tried sucking on the pipes and the bars move perfectly .

I removed the pipes from the carb tune whilst engine was running and there was definitely vacuum on all four cylinders.

I'm at a total loss now?? Any ideas?

Evening,
Would an incorrectly set up bank of carbs cause this issue? I.e if it's running rich or lean?

I'm at a loss now and figure this could possibly be a cause
