Introducing some of the maintenance methods we've received from the MOTO HACK MAINTENANCE campaign that we'd like to refer to. Maybe you can have an idea that you'd like to try!
In this article, I'm going to introduce the maintenance HACK from Webi-man who rides the ZRX1100.
Motorcycle introduction and its maintenance
About the motorcycle
It's a 20+ year old ZRX1100.
There are a lot of things that bother me about the old one, but I maintain it frequently to keep it in good condition so that I can ride it comfortably.

Learn more about the working process
1) Remove the fuel tank.
2) Remove the hoses and caps attached to the carburetor's negative pressure extraction port and connect the vacuum gauge hose to it.
3) Connect the sub-tank to the fuel hose to supply fuel.
4) Start the engine and warm it up. When you start the engine, close all the valves on the vacuum gauge. If you start the engine with the valve open, the vacuum gauge will be broken.
5) Once the engine is warmed up, open the valve on the vacuum gauge.
(6) Opening the valve will cause the needle to shake violently, so tighten the valve until the needle shakes slightly.
7) The #1 was a little low, so first turn the adjustment screw between #1 and #2 to align #1 and #2.
*Turn the adjustment screw a little at a time. Turn the adjustment screw a little bit. It's a good idea to mark the start position.
8) Once #1 and #2 are aligned, turn the adjustment screw between #3 and #4 to align #3 and #4. Then turn the adjustment screw between #2 and #3 to align #2 and #3, making sure all cylinders are at the same pressure.
*Pressure difference between cylinders is within 2.7kpa
9) Agitate the throttle as appropriate to see if the pressure rises in the same way.
10) When you get tuned in, remove the vacuum gauge and sub-tank and put the hoses and caps back in place.
11) Install the fuel tank and you're done.
Advice
Turn the adjustment screw gently and slightly. If you turn the screw too far and it becomes unintelligible, remove the carburetor and visually adjust the throttle valve opening and try again. This work needs to be done with the motorcycle body level, so use a maintenance stand to keep it level. The engine is hot when you remove the vacuum gauge hose, for example.
I don't use the vacuum gauge often and it only comes up once a year, but I'm glad I took the plunge and bought it because I can check the idling, etc. whenever I'm worried about it. As for the fuel sub-tank, I needed it at the time I bought the vacuum gauge, so I made it out of an oil jug and a surplus fuel hose to save money. You can buy a proper one for a couple of dollars, but it's still available, so I'm using it somehow. In addition, you will need a long screwdriver, but I bought mine at a 1 USD shop. I think it's enough because I don't turn it with all my strength.
I was concerned that the idling had become a bit erratic recently, but this work has stabilized the idling. You will need some tools, but I think that if you adjust it regularly, you will be able to run the motorcycle comfortably.
