manometer question

[Wannagofast83]

Has any one made a good manometer? I was looking at some and wondering why you cannot use a vacuum gauge? just sync the gauges to about the same movement.

I made some gauges work one time but they bounced around alot.  I still have them but purchased the motion pro fluid filled version.  Seemed to be easier to use and balance my carbs using the motion pro.

There was a setup where you buy like 30' of hose and throw it over a roof rafter or tree branch, and drop it into a bottle of oil, then use zip ties or a hose clamp to squeeze the hoses to steady the bouncing around
I dunno look arpound some redneck should have done it. (not me, I plead the 5th)
Cool.

Legit thought "manometer" was a joke, like questioning ones masculinity, "man-o-meter".

tons of homemade versions on youtoob.

having just made one based on a yootoob concept i think you need to use glass bottles. the vacuum will likely just crush the plastic sort and then the liquid will get into the vacuum system.
Someone did suggest you put something antiseptic in the liquid (i used someones homemade gin, about 1:5 with tap water) or after a while on the shelf it'll go manky. otherwise the two bottles + pipe concept is cheap and should be accurate enough. just make sure the total volume of liquid in the 'meter is less than the total volume of one side, that way the bike cant ingest any metering fluid.

IMHO it's easier in the long run to buy one. I've had a Morgan Carbtune for years and it works well. For less than $100 it's a good tool for your toolbox.

Love the headline on their website.

The £ British Pound is still low against the $US and other currencies. It's a good time to buy if you live overseas. Now the Carbtune Pro comes with the Toolpouch, 5mm and 6mm brass adapters, 4 x nitrile hoses, restricters, comprehensive instructions and warranty. Carbtune Pro is £68 British pounds + £2 P+P UK, £3 airmail to Europe, £5 airmail to USA, Canada, Australia, N Zealand, Japan. £12 Rest of World - Delivered price to USA is about US$95.  The £ pound is weak since Brexit so take advantage.

I guess they really know how to make lemonade!

They do have a quirky sense of humour [sic], but the tool is a quality product. I've used it on a number of bikes.
