I am going to show you how to mahe $5 motorcycle carburetor synchronizer, and see how well it works at balancing a set of motorcycle carbs on a 1980 Honda CM400.

Did the tubes fit right into the sync port or did you need an adapter? I have 1980cm400a so what worked for you I'm assuming will work for me lol
@scottjones54555 жыл бұрын
I too have a 1980 cx500. It's about to turn 20k miles. The original owner must have kept it in the garage because it is in top shape. The guy I bought it from was the second owner. He knew nothing about maintenance and had just had the valves adjusted and carbs rebuilt so I'm probably good to go for a while, but when it starts running rough, I'll know what to do. Great video.

A good monometer set up because of clear hoses to carbs NOT connected directly to carbs (just to top of bottles) so liquid doesn't get sucked into engine.Nice one ;)
@boomerguy99355 жыл бұрын
I just sync'd my dual carbs on my 1988 Honda Shadow VT600 VLX using your procedure and manufacturing instructions for the homemade manometer. It worked great! One suggestion: Don't overthink the CW vs CCW thing about the adjusting screw. Just watch the tiny bubbles in the crossover tube (I used red ATF instead of water) and you can see the direction of flow. This is much quicker than waiting for the level to change in the bottles. Also, my screwdriver had to be in a vertical position, pointing downward from where the gas tank was attached ( had to remove the tank which turned out to be a good thing because I discovered a leaking petcock) which put weight on the adjusting screw, so I removed the screwdriver after each adjustment. I also "blipped" the throttle a few times throughout the adjustment. Total time of actual adjustment was less than 10 minutes. I don't know if it made a difference but I reinstalled the air filter housing after installing the brass adapter tubes and clear plastic fuel lines (5mm ID) for the adjustment.

@snatr2 ай бұрын
That is cool. I gotta try this! Was thinking about using a light oil instead because if you watch @7:00 when you rev the engine, you'll actually see water vapor form in the bottles. Although a little water vapor in the engine is no big deal. And btw, did you know you can actually boil the water off with enough vacuum. Science 😉

@bjamesW3210 жыл бұрын
You mention at the beginning that you don't care for the gauge manometer because the needle keeps jumping around at idle. I wonder if you could simply use a damper in-line? Perhaps something as small as one of the bottles you are using for the fluid manometer or a bit larger? Ultra easy to try anyway. Just a two port rubber plug to stop the bottle and the air volume inside smooths erratic pressure/vacuum changes without altering the mean pressure/vacuum, kind of on the order of an anti-knock riser in plumbing.

Vac gauges are plenty accurate enough, all you are lacking is a small air tap found on fish tank air pumps which needs to be closed down so that the vac gauge just stops pulsating. One for each gauge.
