Hi was just wondering wats a good base jet size to start off with for my 21 oko carb. Block has been slightly tuned i was thinking bout starting off at 120 and adjusting it from there as needed. Any info would be apreciated Thanks

jetting isnt the same in all engines.. you need to try by your self what jet is the best for your bike, jetting takes time.. yes, starting by 120 is fine, i started mine by 130 and im using a 140 on my oko28

I know how to jet a carb in just looking for a starting point so its easier. I have every last jet so it dont really matter too much just was looking for some help i know every engine is different and mine wont run the same and might not work with someone elses jetting thanks though.
