Question about 2002 Yamaha YZ 426 F
Hi and welcome to fixya,
You'll need to do a maintenance check on the carburetor. For a quick solution to your problem, you'll need to drain the fuel form the carbureator to eliminate deposits. Second, you will need to adjust the fuel-air mixture on the carburetor (set it around 2.5 to 3 turns out) or if it hasnt been changed, leave the stock configuration. Third and this probably will solve the problem in most cases, adjust the idle.
If all else fails, dismantle the carb, remove the fuel reservoir and remove the jets and clean it manually using compressed air.
hope this info helps
