Need Help Builing a Carb Sync Tool with Vacuum Gauges

[valk2128]

I am in the process of obtaining all the materials I will need to build a carb sync tool for the Valkyrie.  I have located several sources for the vacuum gauges.  Where can I purchase a damping attachment for the gauges, or how do you damping the vacuum so the gauges do not bounce all over.  Any suggestions on the gauges and other materials I will need. 

Any help is greatly appreciated.

I bought one off of ebay for my goldwing, it was about  $100 and included 4 or 5 different types of screw in tubes of various threads for the different carbs, all the vaccuum tubing you would need and they came mounted on a board with a lanyard to hang on the bars and the damping guages are built in. They work great, and all guages read the same as I tested them all on one carb with the same reading.
Money well spent in my mind.

I am sure they make one for the valk.

Get a board, plywood, large enough to hold 6 gauges, 3 on top and 3 on the bottom.  Stagger em, as you will see why later.  Especially when you are  routing the copper tube to get to the bottom of the board.

Out of the gauge, the one I built and sold, I used soft copper, long enough to get to the bottom of the board, there I added little valves that could be open, closed part way or shut totally, this controlled the flutter of the needle, and off of those was a healthy length of plastic hose.   Actually it was a neoprene type I got from Auto Zone.    Put 2 screw heads in the top rear and added a piece of twisted cable, picture hanging stuff, so as to hold it up where I could read it.  I usually hung it over the mirror and watched it as I made adjustments....

If we can get to the old Tech Archives, these is a picture of one there that I copied.   I believe it was one of the lads from across the pond who made it.

Also, BIGBF has one he made that was just like mine.

Might get him to take a picture of his and post it.

Thanks Buddy............

I had to buy ten vacuum gauges to get six that were all matching. Wasn't a problem since the gauges were less that 4 bucks each (brand new) and installing them on a common manifold to check for similar reading was a cinch.

Chocking down on the hoses with hemostats was the answer to bouncing needles. Slowed down the reaction but did not halt movement.

Here is the link to the archive I believe RJ was referencing, with the gauge package by DAG (a lad from across the pond).

Any hard ware store has little brass needle valves. Just ask. Find the ones that will fit into your vac tubing. I just bought 1 vac gauge and a needle valve. Works good and only takes 10 min to do all of them.

You can always do what I did. Buy the set of 4 from JC Whitney for about 120 and download instructions from "Shop Talk" section on this site that tells you how to sync using 4 gages. They come mounted on a metal bracket, w/ 4 damper valves (1 per ga.) and works great. Just did mine a couple of days ago.

Ride safe and keep the shiny side up and the rubber side down.

Ricky-D ...... Where did you find the gauges for $4

Ricky-D ...... Where did you find the gauges for $4

I got mine from Nothern tool catalog and look similar to his. Mine was right at $7-$9.
I have a 4 col Mercury motion pro vac gauge gathering dust. Make me a offer and contribute to my Sturgis fund. Never had luck with it. Seemed like i would always suck up Hg. Anyone want it?
