Hello sorry didn’t see ur post earlier. The jets I found on eBay just do a search for pz22 4mm jets should come up u will need main jets and pilot jets. I was running 98 main and 36 pilot but was running rich so I’m down to 90 and 30 and needle on bottom air 1 1/2 turn out. After checking the spark plug notice bike was running lean, re-jet is main 92, pilot 30. Will update after test driving. The extra hose that comes from the middle of the oem carb and goes into the charcoal canister u run to the top plug in the Pz22 carb just like in the pic, the hose in the back of the canister just run it up to under the tank to the tank overflow connection. It’s under the tank in the middle of it. Hope this help u can email me if u want at
