Jets needed for mikuni VM26 (hawk 250)
I just bought a mikuni carb (VM26) and jets from Hawk250.com. It linked me to Amazon. I go to install the jet but it will not screw in. Does anyone know where I can get jets for a mikuni (VM26) carb with fine threads? Or jets that fit that carb from hawk250.com? Please help me!

Have a picture of one of the jets? I can tell you if you have the right ones fairly easily.

measure the tip of the pilot yet to make sure it's not the VM28/486 pilot instead of the N224.103. They are the same basic specs, but the VM28/486 has a 2mm tip vs. a 2.5mm tip of the N224. My Mikuni clone uses the VM28/486.
The jet you have looks like the N100.604 main, which should be the correct jet. I have a suspicion that the Jet kit sold by Wings (amazon seller) sometimes contains the Keihin small round jets, which look almost identical but have a very slightly different thread pitch. They will both still work, but will be very tight on the threads screwing into the emulsion tube/needle jet. The reason I have this suspicion is that I run genuine Mikuni jets in mine, and they screw right in without ever getting tight. The wings jets from Amazon never did. It will be a little bit more expensive, but if you can, buy the genuine jets. There are 3 main sizes that will work for 90% of the hawks depending on altitude. If the bike is completely stock pick up a 25 and 27.5 pilot jet. The 25 is a touch lean on my bike with a pod filter and exhaust, but will probably be better for a stock bike. Main jet sizes. For a stock bike a 105 and/or a 110 main jet. Modified a 115 and maybe a 120. Obviously, your altitude will play a role in what jets to run as well. Later on you can try to fine tune the jetting more with the between sizes like a 107.5, 112.5, 117.5, etc.
