We design our Heads and
Engine Kits with a FULL knowledge of the
engine's operating characteristics and, most importantly, the
application and altitude at which the engine will be performing.
specialize in HIGH ALTITUDE applications
but actually do more low elevation heads because there are more
low elevation riders than high elevation riders.
We ONLY design TRUE hemispherical combustion chambers
with dedicated squish band. With a
true hemi -chamber, your engine can realize its maximum
potential. Most other aftermarket heads are of the Flat-Top
chamber design. This is mainly because they are more easily
As of 2009, our combustion chamber
is patent pending. YES, the design is unique enough to be
patented... as of 2011 it has a patent!
We do not
offer online ordering because we want to speak with EVERY
customer to be sure that they are getting best possible
service and components for their engine.
We can design an engine package that will fit the
type of riding that your engine will be subjected to. For example, if you run a
snowmobile at 9,000 feet and mainly boon dock and climb hills, we will design a
kit that will increase performance from initial start to peak torque RPM. If you
mainly run lake races at 1,000 feet, we will design a kit that will
provide increased performance from peak torque to maximum over-rev.
We can also design a head for any octane requirement you need. If you
have a particular application in mind, call us and we will make a custom
chamber specifically for your engine. The combinations are endless! We
can also re-shape your stock head's chamber. Note: Not all stock heads
can be re-shaped to the "Hemi" design.
We are one of the only companies that will design and fabricate a head
based on the application of the engine. Now, think about that, why would
you want to buy a head that is "generalized" for all applications?
Would you buy a compact car to be used as an off-road rally racer? OR
would you buy a car that was designed for off-road racing?
RK Tek takes a different approach to 2 stroke
engine building than most others. We use to get all "bogged down" with the
"theories" that surround 2 stroke engines. Oh yes, we can speak theory with the
best of them... What we shortly determined was that all those theories and
formulas were based on engines from the 70's and 80's and do not apply to the
modern day 2 stroke engine. The 2 strokes of the past were air-cooled and piston
port induced. 2 stroke exhaust systems were in their early development and
primitive compared to the exhaust systems of the 21st century. The modern 2 stroke engine
is water-cooled and reed valve inducted and has a very sophisticated exhaust
system in place. A FAR cry from the engines the books were written about.
So, we developed some theories and formulas of our own that more closely mimic
the modern 2 stroke engine and differ, sometimes greatly, from the books and SAE
papers of the past.
We focus on internal engine flow and engine efficiency. We strive to increase
the efficiency of EVERY function of the engine. By increasing efficiency, one
MORE EFFICIENT = MORE PERFORMANCE!!!
It IS that simple!!
The more efficient engine also does not suffer form narrow engine power-bands.
ALL our engines will have a very wide operating band and will not be finicky
with elevation change.
