01 yamaha tt-r 125l trouble

Lately its been getting hard to start my bike and doesnt seem to be getting any gas to the engine. Any ideas of what i should do?

Some more info would be nice. Does it start and then sputter out or just not start? Sometimes you can foul the plug on a four-stroke so you could take a look at that. Have you taken the carb out and checked for any abnormalities?

check the jets in the carb b/c if their clogged, the engine won't get any fuel.
