[QUOTE="bclapham, post: 473236, member: 25565"] jman....if what the mags were saying about the 02 not having enough bottom is true, it sounds like the remedy is to lower the port timing to boost the lo to mid (i am still very much learning, but this is how i understand it!:)), amongst other things. did you notice epoxy in the transfers....my low to mid YZ job had quite a bit....it also had a lot of material removed from the intake and boost but what looked like very little (just cleaning) on the exhaust side of things.......dont you just love that crisp new top end feeling. hopefully eric will chime in at some point and explain how/why the mods work.....this sort of thread makes good reading enjoy it dude!
