Hello I recently purchased a boom a few months ago and did a cafe racer rebuild on my bike. After replacing the muffler and air filter I knew I would need to re-jet the carburetor.
The PZ20 that came originally on the bike wasn’t able to tune properly.
So after finding this thread I saw someone bought a new carb but doesn’t say what specific carb they bought or if they had to re-jet it as well.
I found myself buying a Mikuni Vm22 copy from amazon with 48mm bolt spacing. I knew I was going to need to re-jet this carb as well and thought I would have better luck finding jet kits for.
After opening and researching the jets that it came with, I found it has a Mikuni 95 main jet and a Keihin 38 pilot jet. I bolted it on just to see what would happen. It starts fine while on choke but when you take choke off it’s RPMs skyrocket and stay extremely high. I tried adjusting the air screw but nothing changes.
It able to ride smoothly and goes through all gears as if normal but choke is on.
I was hoping someone here would be able to give advice for my issues. Thank you
here is the link to the carb i bought, i have also attached pictures to show.
