[QUOTE="dnchevyman, post: 1056768, member: 65906"] Ok, my 2004 YZ 250 blew upin the dunes a while back. i sent the cylendar off to ALBA racing to get ported, just got it back. the guy at alba told me to go up 2 jet sizes and move the needle clip up at least 1 notch. when i took my carb apart it had a 68 jet in it! doesnt a 04 yz 350 come with a 70 or 72? and when i took my needle out the clip fell off!! i had extras, but i didnt notice what notch it was on! HELP! I put it on the 2nd line down from the top, does this sound ok to you guys???? bike has a moose air filter, fmf fatty pipe, yamaha works port job. main jet went from a 60 to a 78, set the needle at the 2nd grove from the top. Any ideas if this sounds right? :bang: please help and thanks a ton! [/QUOTE]
