Do not turn on hot

Hello everyone, I have a problem with my golfite 91, to see if you can help me? In cold I turn on to the touch, but after walking for a while I turn it off and no longer turns a click, I wait for a while and turn on again, I already changed ignition coil and I put a resistance, I changed the monkey, the cables and disruption cover and the starter engine is one hundred, some idea that it can be, thanks ..

The temperature is normal ...? And incidentally tell if you have CNG?

The temperature is normal and because it is carburetor, it is not the truth that it is the CNG,

Check out the starting engine when they are hot spent, only the solenoid is heard

Compa Preblema is the starting bike
