cutting the rest of the holes. Cut the template from
the back of the manual. Center the hole for the valve
cover over the engine, and then tape the template into
position. Use a pencil to mark the holes in the template
directly onto the cowl.
If using a different engine, take measurements, make
templates or simply “eye” the locations for the rest of
the cutouts using a pencil to mark them.

10. Cut the holes little by little as you continue to
fi t the cowl, checking the size/position of each cutout.
As the top photo illustrates, the front of the cutout
for the valve cover needs to be moved forward, so a
mark was made and the cutout was adjusted until the
fi t was perfect.
❏
11. Use the included plastic template to mark, then
cut the hole in the front of the cowl in alignment with
the engine for additional cooling.
❏
12. Once you have all the holes cut, smooth the
edges of each cutout with sandpaper. Here’s a look
at the cowl with all the cutouts. Note that, for the O.S.
.91 4-stroke, the muffl er will have to be removed for
installing or removing the cowl. If you prefer not to
have to remove the muffl er, simply extend the cut all
the way back to the end of the cowl.
INSTALL THE REPLICA ENGINE
Refer to this photo while working on the replica
engine.
❏
1. Use a Dremel ® tool with a carbide cutter to rough-cut
one of the cylinders from the replica engine. Follow with
a small drum sander to even and smooth the cut edges.
❏
2. Sand the edge of the engine all the way around
where it will contact the inside of the cowl so glue
will adhere.
