Don't buy those they're rubbish!
Spend a bit extra and get something that works like these.

I already had a set of morgantunes for a twin and thought I'd save a few quid when balancing the 4 carbs on my Indy by buying the gauge type.
They are utterly crap and are still sitting on my shelf unused after the first couple of attempts to use them. They're about as accurate as
listening to the carbs. I'd have binned them but it seems a waste of money!
I bought a set of 4 Morgan tune balancers for £50-60 and they are just miles better.

Never had a problem with them, and have checked them by balancing the carbs then swapping the pipes.
Have lost a couple of the restricter valves, so if you want to flog me your gauges, I have a use for them..

Maybe there are different levels of quality out there - the ones I got seemed pretty poor. Which of the restrictors do you need?

I've used one of those as well and IMHO the Morgantune set is well worth the extra.

Whats wrong with pipe and ball bearings?
Have a search, plenty of solutions for pennies, you are not measuring pressure (or lack of it) just difference, if ball bearings scare you then water
in the tube.

Simplest balancing tool is four lengths of aquarium pipe with some coloured dies. Jobs a good'un.
Otherwise the Carbtune is quite a nice bit of kit. MAP sensors are awfully expensive. You don't need an actual value after all, just to make
sure they are balanced....

reason for asking is that I have one ot two map sensors; wiring them up should not be that difficult; using DVM to read pressue would be all that I
need.
