I have a 84´GPZ 900A1)I used to have cooling problems)"Fixed". Now I have a knocking sound when I first warm up my bike. I take off and give my bike alittle throttle from 2nd gear to 3rd. I hear this knocking noise.Then when my bikes all warmed up it goes away. I adjusted my valves.I run Pure Synthetic Oil. I use gas octane boost additive. I changed the igniter box but I get this weird knocking noise when I first start off in the morning.It almost sounds like a rocker arm noise.Any remedys out there for this problem??My bike has 37,770 miles on it.
