i have a 79 kz 650e and i just got it back together and fired it up for the first time and it starts but the pipes on num.1 and 3 are cold. so i put new plugs in and nothing. and checked spark it looks good and the plug was wet so i know its getting gas also checked compression and it reads 80 psi with three good kicks. i dont know what else to do or check. one other thing it seams like after about ten min. of runing the pipes are hot but i think its just because its hot from runing, i dont know? any help with this would be great thanks john.
