Favorite Carb Sync Tool?

[dieziege]

I've got to sync the carbs on two bikes ('06 Kaw EX250 and '79 Yam XS1100) and I'm looking for advice on good all-around carb sync tools.

I know you can build them a few different ways fairly easy... that's one option. There are also a few different versions you can buy, ranging from oil-filled to electronic.

I'm just wondering if anybody here has a special favorite, and what makes it so?

I like the ones that work, and the reason is obvious

This is not realistic for you home mechanics, but I just talked our shop into finally ordering the VacuumMate. It's an electronic synch w/ tach and also helps you detect leaking valves. The thing is trick. I wanted to buy one for my personal use but at around $400+ I passed. Now I got the shop to float the bill.
I was using the Motion Pro mercury sticks before that and have it for my home use. It's fine except everyonce in awhile the mercury would puke out from the vent. Great, I'll probably be dead in a few more years.
Never really considered making one since it's my livelyhood and am not afraid to buy tools!

$400 is a bit much.

I was thinking more like:

TwinMax
Uni-syn
Homemade #1
...and of course we've all seen the mercury versions...

I have a Motion Pro 4 tube mercury synchronizer.

Very easy to set up, very easy to use, and very cheap. With electronic synchronizers, you have to hope that whoever built/programmed them got them calibrated properly.

Can't really screw up a good quality mercury tube synchronizer. Only trick with them is that you have to store them upright, but they come with mounting holes that you can use to hang them on a wall or even build them into a stand.

You should just go with the Homemade.

Although, I use this - No mercury. http://www.carbtune.com/
