i am just doing the final tweaks and dial in on a 1971 cb100 with the same lifan200
i got the set motor but the supplied carb sucked
so i have now replaced it with a vm28 mikuni
i have a custom exhaust while the jetting dial in is not perfect yet
Do you know exactly what Jets you used? I am completing this engine swap on my fully powder coated and restored sl100 and I am having issues getting it to run right with the Mikuni VM28-418 flatside carb.
