:sup Hey Guys anybody try the dial a jet on the YFZ 450? I have 400EX with one installed & man does it work GOOD & installed EASY! The only reason I havent put one on my 450 is I don't see much room on the air boot to install. If anyone has got one on their YFZ 450 or know someone who has put it on please respond. Thanks

Yes. The company that makes it tells you, that once you getting your jetting dailed in like you like it. From there you genraly jet down 2 sizes on the main jet. I had 1 on my old 300ex, & put 1 on my sons 400ex worked great! But I still don't see much room for instalation on my YFZ 450. It is EASY to rejet from there; if need to just loosen 1 scew w/ flat head scewdriver the turn the clicker left or right to rejet.
You also have 5 differnt setting with it! Never had rejet the main jet again. EVER! I think if you could install it on the YFZ would you see WAY less questions about jetting! May I'll take the 1 off my sons bike & see if it fits, Then do a post on it.
