Anyone used this Carb Balancer?

[aesmith]

Hi,

I saw this rig advertised on Ebay, using a different principle to the normal multiple vacuum gauge devices.

http://www.ebay.co.uk/itm/UNIVERSAL-MOTORCYCLE-CARB-BALANCER-VACUUM-GAUGE-TOOL-/330904726447?pt=UK_Motorcycle_Parts&hash=item4d0b756baf

Instead of measuring the vacuum of each intake, this device measures the difference between the two. It also looks like something that could be improvised with some clear tubing and a suitable ball bearing.

Just wondered if anyone had tried this device or anything similar. If not I might have a go myself if I don't find a secondhand "proper" set soon.

Your link is a little funny for me:

Not used that type myself, have used others.

Not sure why it minced my link, should be fixed now.

Get yourself a 2nd hand Carb tune, they're the best.

Got mine on Ebay, even if you buy one for 4 cylinders, you can just use 2

I've seen both good and bad reports on the Carbtune (mainly good, but not all). Are they really worth twice the price of the gauge type sets sold for around £25 by many people? Carbtunes seem to go for pretty high prices second hand, well over £25, and of course there's no comeback if it turns out to be a duff set.

I don't even know if mine need balancing, I'm just assuming that since the previous owner did his own maintenance, it's worth checking.

We'll the fact that you've read mainly good reports says it all.

Even if its way above £25, its cheaper than taking it to a garage.

I've had cheap gauges before, and a waste of money.

You can make your own gauges out of tubing & a fluid I can't remember what.

I'm sure it was a thread called something like DIY vacuum gauges.

Once you've balanced your carbs once, you'll understand how nice your engine runs with balanced carbs.

Install some of Bibio's vacuum line extension tubes to make it a 5 minute job in the future

why over complicate stuff.
use the "two bottles " method.

[aesmith]

OK, now that's low tech. I might try something like that, but I'm starting to get the idea that a Carbtune is probably in my future sometime.

What sort of vacuum does the engine produce? Just wondering about column heights for manometer type gauges.

Thanks, Tony S

It might be low teck. but you can't suck fluid into the motor.
cheap and effective.

[aesmith]

Another quick question, can anyone tell me what inside diameter the vacuum tube needs to be? Save me dismantling everything to measure, then a second time to fit the tubes.

Send Bibio a PM he made up the vacuum hoses, so he'll know

I think its 6mm
