i have a blown motor now but am going to rebuild and i want to build the ultimate trail motor. I ride in very tight trails with trees, rocks, and water everywhere. i want the motor made for trails only not for dunes. i was hopig you guys could give me some ideas and maybe try to keep them as cheap as possible. i know that cheap parts are cheap but i dont want to build a $3k motor that my wife blows up. the cylinder has been bored 9 over due to first blow up. it has a fmf fatty pipe and turbine core 2 silencer, k&n filter, boysen reeds, and reed cage spacer. everything else is stock
