i have an 1989 fzr 1000. in two years i´ve blown the motor up 4 times. i´ve replaced the motor with a fresh 1990 fzr 1000 motor and have had the same problems. the #2 cylinder keeps burning up the bearings on the crank. ive heard that this cylinder is known for problems with oil and oiling ports. does anyone know how to fix this issue?
