There are some things to check....
Compression test
Clean fuel filter screen in pet cock
Clean carb vent lines
Check fuel tank vent line
Check fuel flow to carb when cold and when it dies.
Thanks for the quick answer! I think the problem is the flow, when the gas enters the bottom chamber of the carburettor. That it is limited in some way, so it flows slower than the bike uses gas.
