Default Hesitating when hot

I have a 1979 kawasaki KE 125 that runs great when the engine is cool but once it gets to full temp it seems to bog or miss or somthing.... im really not sure how to discribe what it does...
Right before the powerband kicks in it like hesitates...
It seems like a lean condition to me... like maybe crank seals.
the jetting is fairly good..
The plug is a medium shade brown color.. slightly carbony.. but not any where near fouled...
I will try a new plug today but i dont think that is what it is....


This bike runs on premix, and has a newish top end (~10 hours)
Any ideas?
Other wise this winter i might split the cases and put in new crank seals and mains....Thanks
