So, I'm confused. I am running an 82 jet on my 70cc maxi with a 15mm bing. I am trying to upjet because with the 80 jet, my plug chops were waaaaay lean. Really white. However, with that same 80 jet, the ped ran really well. Nice low and top end. Now, with the 82 and also with an 84, it runs the same up to half or 3/4 throttle (runs well), but the top end is boggy beyond belief. I can't even really do a decent plug chop with these bigger jets because it'll die when I give it too much throttle for more than a few seconds. What should I do?
