building a synchronizer for motorcycle carburetors?

[Nostril Cheese]

I've just picked up an old Honda as a project bike and was wondering if anyone knows how to do this. I remember reading something years ago saying all you needed was some tubing and it worked similar to the way a level does.

Any info? links? The carbs in question are Keihins.

Thanks

It would be easier to buy them. The ones you can buy have 4 small diameter manometers about 3 feet tall with mercury as the fluid.

google "slack tube manometer" and you'll see how to make one.

I bought one from Ivan's for 70 bucks - here's the link.

Good stuff. Works well. His jet kits are the shiznit too.

My heavy breathing R1100S sucked the mercury out of mine. I put my feelers out for some and ended up with some extra. The local science teacher used it for a bit but gave the jar back.

I have a Motion Pro one. I think it was about $20-30. I got the economy model. Never had a problem with the mercury getting sucked out. Now my bike's injected, so it's just collecting dust in the basement.
