well me and my dad usually do all the bike work during the week. we usually change oil ever 2 to 3 rides airfilter all the usual bike work, since its 4 days before the loretta lynn qualifier we took it to my engine builder to have him go through it. he said he found some dirt, which broke the reeds, and then the reeds got sucked into the cylinder and bottom end. so all in all it was a snow ball effect. its ok. i talked to my mom, we are either buying a 2011 250sx, which there is only one in washington, or we might get a 2011 250f so i can ride the national if i get my pro points in time, and fix the 250 2stroke to race and practice on.
