[yz250guy]

I have one, but my jetting is still out of wack, so don't want to post until I get it dialed. I can tell you, it's a 96, Mobile MX2T @ 32:1, boyesen reeds, stock pipe, FMF PowerCore2 SA.

a buddy of mine has a '99 yz250. he runs belray h1r at 40:1, vforce 2, fmf fatty, fmf shorty. i'm not sure what jet sizes he's running or how many turns out the air screw is. if you're wanting jetting comparisons, you might also want to ask elevation as well. here in dallas we're between 500-700 feet above sea level.

Just about every year Yamaha has different jetting specs to go with the updated motor changes.

Hi All,
