by the way i just joinned this site, and have found some very good info thanks to everyone. i have a foreman 500 4x4 09 manual on the floor solid rear end basic bike. anyway its not even 3 weeks old and allready had something break inside the trans. i think not sure it could be the rear end. when its in gear 1st or rev. it makes a very bad noise like something in it snaped. but the tires still want to spend so i dont believe its the drive shaft or the rear end. has anyone had this promble or know what could be going on. any help would be great thanks.
