Wanting to change Exhaust header and air filter to some performance one's but was reading that I would have to change the Main jet in the carb, if so to what size? I was told by AGK a 108 would that work? Keeping engine basically stock, but have to put different exhaust and air filter to fit engine in the frame...Thanks
 
I would guess a .040 jet would be about right. Just a guess if you have open air filter and header. That would be a 100 in Honda speak. I feel a 108 would be a little big but I don't know a ton about 340s. Good luck
