AS OF 2005.. RK Tek is porting cylinders using CNC Vertical Machining Centers (CNC porting). This assures EVEN porting and proper flow!
HERE for pics of the CNC porting.
2 Stroke Engine Porting: if it is to be done right, is a very
complicated task. Careful care must be taken to assure that engine will
not end up making LESS power then it did before the engine porting was
RK Tek uses the latest in 2 stroke design and simulation software,
coupled with, practical knowledge that can only be gained through
experience and trial and error, to properly modify any engine. These
simulation programs require an extensive number of engine parameters and
measurements to be inputted before they can effectively simulate
realistic outputs. NOTE: These software programs are just a tool!
BUT, when these "tools" are used , in conjunction, with real world
experience, you have the receipt for a proper engine modification.
Some engines have exhibit obvious areas, that do not require running
simulations, that need alterations. These areas are the ones to address
RK Tek will not let these engine jobs deter focus from, what we feel, is the most important aspect of engine tuning... COMBUSTION!!
We feel that with MOST modern engines, greater improvements can be
made in modifying the combustion process that any other area
--->>> including porting.
Therefore; we ,currently, only do a limited number of engine porting
packages. We only port engines that we are VERY familiar with. We will
be the first to recommend another engine builder for porting services if
the engine you need ported is not one that we have some experience
RK Tek has a full-time porting person in house.
If you have an engine you feel requires some engine port work.. please
feel free to contact us and see what our schedule looks like.
For you snowmobile people, the best time to have your engine ported by RK Tek is in the Winter off months.
RK Tek spends much time developing SOLID porting packages to compliment
the head. This R&D is all done on the mountain where one can SEE
REAL results. Using a dyno for porting is not the best way to develop
"Real World" power enhancement. Although, we do utilize our dyno, it is
always secondary to real world testing on the snow!!
At RK Tek, we tend to look on porting a bit different than most other
porting houses. We REFUSE to alter ANY engine, via porting or other
modifications, to a state that makes the engine "PEAKY" or have an
explosive power hit. We have discovered a special type of porting
alteration that allows for a very smooth power delivery and NO sacrifice
of low end power and especially no sacrifice of engine reliability.
