[QUOTE="YZcarver, post: 52021, member: 744"] Did you read the pdf I linked? I think you did, just checking that you're not talking about the image. [URL="http://www.fmfracing.com/Content/Instructions/Jetting/YZ250%20jetting%20%28000346%29.pdf"]http://www.fmfracing.com/Content/Instructions/Jetting/YZ250%20jetting%20%28000346%29.pdf[/URL] 450 does seem huge unless your bike has had other work done to it. Honestly I would note what you have now and try the settings FMF suggests. If they are way off, you know where to go back to. @2smoke: If he's running a 450 main, it's a Mikuni. According to the link above, based on the numbers, Yamaha switched from Mikuni to Keihin in 95. [/QUOTE]
