89 kx 125 again!

[1966mustang]

Ok i have a bogging problem with my step dads 89 kx 125. It bogs and dies sometimes when im at slower speeds and rev it quick. The bike runs perfectly and is wicked fast other than that problem it is fine. I have done a couple things to try to fix it i changed the jetting (made it richer), looked at the kips valves and the teeth were stripped on them so i bought new ones and cleaned up the places where the valves sit real good so they turned great and lubed them well, ran better gas, bought hotter plugs, and still no change. Please Help

Do you think you may have made it too rich? It may take a fair amount of tuning to get it just right. Are the reeds in good shape?

i never really looked at them and i dont know much about them but i just took em off and they look fairly good in my opinion. ill post some pics later hopefully.i had a 155 in it went to a 162 and 52 pilot stayed the same. Any other opinions?
