We are one of the few shops that is not "scared" to get in there and
actually do some "REAL" changes to the cylinder's porting arrangement!!!
We do NOT just send you cylinder back with a polished exhaust port and
charge you tons of $$$$.. We actually modify EVERY (Yes, EVERY) port in
your cylinder to assure the max power and flow characteristics in your
We have spent countless hours R&Din' engines to determine where the
faults are internally. We do not just "guess" at what to do nor do we
just make everything bigger and higher!! ALL port jobs are done using
data we have collected through many years of engine testing!!
The CNC porting has allowed RK Tek to take porting to the next higher
level!! Using the CNC Mill we can assure you that the cylinders are
modified as evenly as possible.
KEEP IN MIND... The CNC only performs the "ROUGH" porting.. There are
still many hours spent on the bench doing the final modifications.
On the average.. EVERY cylinder requires between 3-4 hours of hand work
before it is ready to be returned to the customer
