There should be a full series of numbers stamped in the side of the upper fan shroud.

The large cover that surrounds the too fan screen and goes from one side to the other. Many were red, but some models had black paint according to how the order for the particular brand they were installed on.

The actual muffler and the head pipes were usually separate according to the rider manufacturer.

Is this an engine adaptation project to your existing rider?

Might pull the top engine cover off. Clean the cooling fins. Probably never been off the engine.
