Tek SKI-DOO 800R
and ETEC DIRECT Replacement
DUAL RING Pistons
IF you have NOT read the tech article on the reason behind the power problems of the Rotax 800 Twin Engine
PLEASE, take a little time to read it so that you
can have a better understanding of what is REALLY happening inside this
OK, Now, that you have a good understanding of the problems associated
with the 800 Series III Engine and R Engine.... Let's look at a few solutions to what
plagues this awesome power-plant!!
Our pistons have a geometric
design that is specifically for the
use that a snowmobile engine subjects the piston to... We also use a
different alloy that better suits the snowmobile engine..
ALL if our pistons are
tested for at least ONE FULL SEASON BEFORE offering them to the public.
Using this method, we can rest assured that they will handle the task
PISTON (2016) = 570 Grams
DUAL RING 800R PISTON = 502 Grams
Tek is known for their unique and effective methods for “fixing”
engine issues, this new engine was surely going to get the “full treatment” and
get a “makeover”. This “makeover” came in the form of a new made Dual Ring
Piston and Head Kit to drop in the new 800R Engine.
This Drop In Piston Kit was designed in the same manner as our Series III Engine
160HP Drop In Piston Kit. Remember we also have a Direct Replacement Piston Kit
The power-fade and ring flaking problems VANISH!! with this kit.
This allows for an EASY, Bolt-On, power package that keeps you legal in most sanctioned events.
So, now, we have an engine with a MUCH better piston and ring design.
Couple that with a custom combustion chamber designed specifically for
this engine and you have yourself a recipe for a very SOLID and POWERFUL
power-plant that will NOT power-fade (heat soak) on a long pull. This
kit is also MORE reliable than stock. In other words… It will perform
better and last longer than your stock engine set-up!!!
OK, What is required and what are the costs for this awesome kit?
Tek will send you the kit so you can put it in at your leisure (NO
The cost of the kit is as follows:
Custom 82mm pistons (2) $185.00/each
Base gasket (1): $25.00 (optional)
