Leak Jets?

Does a stock carb on a 2001 yz426f have a leak jet? Is there a website / page ddicated to the yz426f like thumperfaq.com for the yz250f? Thanks

Guess not.

I have an '01 WR and it doesn't have one. I looked at the Yamaha parts fiche and it doesn't appear to show one on the YZ carb either.

Thank you very much for the info. My buddy rides the 426f and I have tried to get him to mess with it to make it run better but he just says " it runs fine now and I don't want to mess it up. My 250f ran perfect but with the little tuning I have done has turned my bike into a beast ( 250f wise ).
