I just put on a full fmf system on my 22 TC 125 and didn’t need to change the jetting. However it won’t be the same for everyone. Also if you have a 22 TC 125 keep in mind that there is a known jetting problem with the bike already. People have swapped the Mikuni with a Keihein 38 carb to fix the problem, but there was also a safety recall for the CDI unit which may be the problem. If your bike needs tuning I have the correct jetting I can send you, otherwise jetting the bike will just be fine tuning. Hope this helps 🤙
@@BurtPizzaRolls Main Jet 490, Pilot Jet 32.5, Needle Jet S4, Air screw 1.5, slide 5.0, Needle 42-74 on the 2nd clip, Power valve 1.75 turns in from all the way out, fuel mix 40:1. The slide is very important for these jetting specs FYI, if you have any questions lmk.
