CARB VACUM GUAGES/BALANCER - BEST ONES?
flatfour:
I've used Davida gauges for quite a few years now - I'm in Norfolk (near Watton) if you want to come and try them on your bike.

The cheap biketek gauges have arrived. What values would I expect to see at idle?

Every bike will give different readings at idle. What is important is to have all cylinders within 2cm mercury of each other, the closer they are the smoother the idle. That said, no point even getting them hooked up until ALL servicing has been done, Tappets, camchain, ignition timing, engine oil clean and at the correct level, air filter clean or new. Balancing the carbs is a waste of time if the other parts aren't done first.

when you start to use the gauges ,firstly fit the brass tubes ,longer for inner pots ,mount the gauges ,ideally across the handlebars,
,I suggest connecting the 4 hoses to the gauges then cut them about 5" from the gauge so you can fit the white taps ,
just connect all 4 hoses to brass pipes ,and your almost ready to go.
have you a method of supporting the tank well above the carbs ?
so you can ccess the adjusters,,and don't worry to much about the reading,just try to get them almost the same .

A remote tank as seen in John’s photo is worth investing in, I think mine was £17 from eBay, one of the best 17 pounds I’ve ever spent.
