Hello, on Dirt Bike's site, someone asked a question to Mr Know it all about the YZF426. The question was: "Q. If you can help me with this problem you'll also be helping about five of my friends. We all have a 2000 YZ 426F and we all have the same problem, if you blip the throttle off idle or low rpm the bike will cut out or die if you don't release the throttle. We live at 1000 ft above sea level in a rather continental climate" and he answered: "I've answered this question already. You and your five friends truly should have known". As I have the same problem, does someone know what his anwer was ? Thanks a lot. Floris.
