Looking at getting a jet kit with the 28mm oko carb but I dont know what range to get for this size motor. Im running a 126 main jet in my 24mm so I can get a pack of jets sized 140-150 or 150-160 or 160-170. Im thinking the 2 larger packs for the 28mm. Am I correct or should I shoot for the smaller sizes?

on the main you shouldnt have to go bigger than 152 and thats for big strokers. you might be in the 138-142 range
