Question Smoke and Hot engine Honda CT125

Hi there, I need some help with my Honda CT125 1987 engine.
Firstly, the engine after a short ride gets so hot that you cant leave you hand on it anywhere for more than a couple of seconds and secondly it smokes quite badly when going up hills.
I have included some pics of the piston (a bit of wear) and also the build up of carbon (I cleaned the carbon off only a few months ago and I dont use it very much). If you have any ideas please let me know!

The smoke is a white-gray colour sometimes with a bit of blue.Attachment 1810 Attachment 1811

White smoke usually means valves, and since oil burns hotter than gasoline you will have to do a top end on that 125. Lots of hop up parts for you bike btw that can make it a real screamer.
A gun is a tool, Marian; no better or no worse than any other tool: an axe, a shovel or anything. A gun is as good or as bad as the man using it. Remember that.
