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.
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.
