INTRODUCTION
As with any other fine piece of high performance machinery, the Hirth engine requires
proper maintenance and care. For instance, it is absolutely vital that proper, clean, fuel and
the correct oil pre-mixed be supplied to the engine. Further, the carburetors must be properly
tuned, made sure of no leaks, must be kept clean and in proper working order, etc.
The Hirth engine is, of course, a piece of machinery. As with any piece of machinery, parts
will eventually wear and/or fail. It is very important to do regular maintenance and
inspections on your engine, inspecting, adjusting, repairing and/or replacing the parts as
required. In which case, the risk of having an engine failure will be minimized.
This manual contains much information regarding your engine, however, it is by no means
complete nor tells every detail, as it is impossible to list every piece of information and effect
that each detail may or may not have in conjunction with all of the other related aspects. As
you can see, the possibilities are endless.
For information regarding a specific topic that may or may not be covered in this manual,
consult with your local Hirth technical representative.

staking experience be in vain. This
information is supplied to you in order to help keep you and your engine safe. It is a good idea
