Can anyone recommend a good CHEAP manometer?

Looking to do a starter valve sync on my G6 VFR. No price is too cheap. Would prefer if it was multi-gauge rather than having to relocate a single gauge between each throttle body. Thanks all!

 

Motion-Pro? It uses man made manometer fluid thats cosmic and blue in colour, anywh-00...How you kill your Ninja 650? sad sad sad ; )

 

Make one.
4 lengths of 6mm clear plastic tube, some T pieces, and a piece of board about 2m tall. Fill the tubes with ATF to about about 600mm from the top.
thats the only drawback, its LARGE, but it works better than the motion pro pos.
There is the www.carbtune.com which looks OK.
The best type is the (illegal now) mercury filled ones, you lucky people that have one.

 

There are lots of youtube videos showing homemade manometers in use. They are simple, using just 2 stroke oil or ATF (automatic transmission fluid) and tubing. for example Carb sync using homebrew manometer. - YouTube This version only syncs 2 carbs and if you have a 4 carb bike, you would sync carbs 1 & 2 then move the tubing once to sync 1 & 3, then once again to sync 3, 4. But it is nothing more than some tubing attached to a stick with oil in it. It does make my Suzuki GS750 idle better when I sync them though. I have not tried doing it to my 2000 VFR yet though.

 

You really need to make/buy one that will hook up to all 4 SVs at once or it will take a LONG time moving a single one a round to get your readings.

 

I made one using plastic tubes and mineral oil (baby oil). just make sure that all the "leads" to your engine are the same length and do not use hose splices. with mineral oil it was about 2 inches on the board per inch of vacuum, so had good resolution but thats not what is important. What is, is that they are all the same or as close as you can make it. if you need to tint the oil to see it just use a colored light buld aimed from bellow or food coloring and lots of it! I also verified by using some slightly expensive vacuum gauges, they work but found them to bounce too much.

 

you want cheap or good
