ABOUT THE ENGINE
Exhaust Header Pipe(W/M10 Lock Nut)
Please note that this engine is not supplied
with any tools (e.g. Allen keys, wrenches, etc.)
This is the first model from the new FS
series of the single cylinder overhead valve
four cycle engines.
It features a sharp and modern look and
broad power band to suit a variety of model
types. Newly designed F-4040 silencer
minimizes noise with its soft, low-amplitude
sound. Threaded header pipe allows
adjustments in the distance between
silencer and exhaust and exhaust angle.
New lubricating system eliminates the need
for breather tubing from the crankcase. It
has the same mounting dimensions, drive
hub position and linkage position with the
FS-52S.
