Why is my scooter getting so hot?

I'm having problems with my Suzuki ay50


It seems to be getting really hot, I took off the plastics to have a look and there's smoke coming from around the head and barrel, the water pump seems to be really hot aswell. I can smell a burning smell coming from somewhere. It has plenty of coolant and the water pump is working fine as I can feel it spinning, I've also tried bleeding the water system but still no luck

Any ideas? Cheers

 

Could be runnin too lean, do u know if it's been up jetted or is the bike standard?

 

is there a temp guage on the bike to say its running hot....remember its silly hot outside so the ambient air temperature isnt enough to cool it as much as in winter. Is the system filled with plain water or coolant mix?

 

I've sorted it lads, somebody had put a stupid gasket in the thermostat cap on the cylinder head and it wasant letting enough coolant through. Thanks anyway!
