Ordered a Manometer gonna be doing this myself in a few days. Oh and i have the control valves so i can steady the needles / reading.

I want to see the Virago all in a whole.

top of the rubber boots between the carbs and the cylinders.

Was posted 6 years ago but fyi manufacture aka Yamaha states sync should be set at 2000 rpm not at idle

Soooo, quick question on this> What would cause one of the two bottles to collapse in, into itself almost instantly after starting the bike with this type of setup? Stuck choke circuit in the carb? Or is there a possibility that a stuck engine valve could cause something like that?

You can't use plastic bottles, unless they are very sturdy. Use glass for best results. There is a surprising amount of vacuum force on these when doing this.

What exactly is this setup? What's going where on these bottles?

You bought this set up? Is that the proverbial blue fluid? What is that blue fluid?

Made the setup myself. I believe the bottles are Snapple bottles. Black corks from the hardware store. Blue silicon tubing from the pet store (used for aquarium air pumps). The blue fluid is just water with a few drops of blue food coloring in it.

There's a screw to synchronize the carbs. Get a service manual pdf, you should find on the internet.

@@avelinovalencia7431 this is not the air fuel mixture screw. This is synchronizing the carbs. Meaning you make sure the throttle valves are behaving the same way in relation to the throttle cable. Twist the throttle on your virago. In the middle of the two carbs you should a metal piece moving around. There's a screw with a spring wrapped around it. That's the one he's adjusting kzread.info/dash/bejne/gJln09Ofh8LKiKQ.html watch this video. It goes in depth on carb synchronisation and why it isn't as important as people make it out to be

there supposed to idle between 980 and 1010
