Hi I have a stock zongshen 155 that I am trying to tune a pwk 28 for. I was using a genuine mikuni vm 26 carb I’d bought off tbolt USA but the throttle response left something to be desired, so I thought I’d try a flat slide since this carb was given to me for free. Pretty sure the carb came off a ktm 85, so it’s a genuine keihin carb. I have a wide variety of jets and am just looking for a baseline to go from. I have a jjh needle main jets ranging from 100 to 120 and pilot jets ranging from 32 to 58. What would be the best combo to start with. I couldn’t find anything for a zs 155.
