i just bought a 99 blaster. im 6'4" 250lbs. i sit back pretty far, and the rear suspension is completely bottomed out the entire time a ride. i tried screwing up where the spring sits, but its up as high as itll go. also i plan on extending the swing arm which will probably make it even worse. anyone know of a spring i could put in there or a different rear shock that is stiffer?
