most of the numbers on the engine can be ignored they are casting type numbers i have a pair of brand new cases yet they have 1vj stamped on them :confused1:
the only numbers and letters you need to know is the first three on the engine and chassis i think it will be something like 4pt on your bike.
if its banging on bumps and all the nuts and bolts are tight the suspension and linkage might need a service, the linkage gets neglected on these bikes so might need new bearings and that linkage mounts to the frame below the foot pegs so it would feel like its coming from the frame.
