Morgantune balancers are excellent an not too dear. They work with bike TBs I think.

Just use your lug hole and a bit of hose pipe!

I used a single vacuum gauge (because I had one) when I balanced my T/Bs just transfered it to each T/B in turn and tweaked as needed. Bit of hose and
lughole work just as well with a bit of patience. Just take your time and recheck after every adjustment.

I thought I'd got mine fairly close with the bit of pipe/ear'ole trick , then I managed to borrow a synchrometer - and found they were a
mile out 
The improvement is worth the work - theiving tweeks and burton do them if you cant borrow one .
Its cuz I is blond , innit

I'm planning on making my own, should be fairly locost.
1 plank of wood, need to work out the length (depends how many mm of water the engine vacuum is likely to pull) but probably 4ft or so. Stand it
upright and p-clip some clear tubing down the length, 180 bend at the bottom and then back up again. Attach some vacuum hose to one end of the tubing.
At the other end of the vacuum hose you need some thing to give you a seal against a trumpet, I was thinking of a dogs rubber ball with a hole
drilled through it, and the vac hose glued in with a bit of silicon. Will need a second bypass hole as well to let some air into the engine while
you're using it.
Half fill the clear tubing with a bit of water (and food colouring to make it easier to read), not too much in otherwise the engine might suck it up.
Stick the ball on a trumpet and mark on the board where the fluid gets moved to. Some experimentation with the bypass hole in the dogs ball may be in
order, too small and the fluid will be sucked up, to big and you won't pull much vacuum in the 'gauge'. Repeat on all four cylinders
This is where someone tells me I've missed something really obvious which means it won't work

I've got a flow-meter similar to this thing:
It's stuffed up the orifice of each carb in turn, starting from the one that's got the throttle cable attached.
When I first ran the engine with the bike carbs I set it up with a length of hose. When I finally tweaked them with this gizmo I found that I
wasn't too far wrong - better with the flow-meter, but not too shabby before.

The trick is hold the hose in exactly the same relative position for each inlet.

I did that - but the problem I found is that the butterflies are so close to being closed a tickover , there was very little difference in sound .
