I have finished re-installing my HKS on my Firestar, with the help of Roger
Hankins, who is much smarter than I, not to mention much more patient.
The HKS is a great engine, but the installation for Kolbs means the muffler
has to be mounted in front of the engine on the root tube of the cage.
Since this thing is about 8 inches in diameter and round, the wind is very
disturbed, and overheating has been a problem. I overcame it by shrouds
over the heads, which kept the heat within acceptable limits. I decided
that failing a better muffler configuration, or a smaller muffler, a
streamlined one would be a help. Streamlining was out of my expertise, so I
just made a flat plate that I attached to the back of the muffler. The
theory being that it would at least direct the air into the heads. Well it
works to the point of about 30 degrees or more CHT temps. I needed to make
a longer flight to see for sure how it was going to do.
The skies were very hazy with smoke, and visibility was not all that great,
but the flight was just fine. The baffle kept things very cool. The highest
reading was 289 at WOT, climbing up the face of a long hill, the average
was about 268, and the lowest was 256.
The water situation here is pretty severe. There are only two springs still
producing water on the Sheep Heads. The only other water is that supplied
by the ranch next door. Wild horses drank most of the water hauled up
there.
The flight covered an hour of time, I flew for 60 miles, burning 3 gallons
of gas. An average of 60 MPH under all the conditions that I encountered,
uphill and down hill.
