Dang.....a pic of the highly coveted Rota-Derp (fresh out of the box) the pull starter hasn't even been rotated yet....
Actually this particular engine has been used on four karts in five different installations.
The finish on these are so impenetrable, that nary a scratch shows after 7 years of use.
It does not leak oil, and even comes without any governor installed.
The extra .3 cc's smears the competition all over the backyard, as well as the track.
With the simple twist of a screw, the output can be changed from a meager 2.5 hp, to a roaring 11 horses.
It will run on diesel, gasoline or alcohol efficiently with zero modifications.
After 9 years of continuous use, this engine shows zero decline in compression using a leak down test.
Using unique BITT (built-in torque technology) this engine is guaranteed to never burn up a clutch.
The spark plug alone comes with a ten year warranty, and with 11 years of use, the plug has never needed replacing.
All internal parts are composed of 100% depleted plutonium 236, including the modulator and flannigan rod.
No other competitor's claims can even come close to this 15 year old engine that has never once been torn down or rebuilt.
The Rota-Derp is the finest engine available on today's market, bar none.
At $93 dollars US, there is just no way you can go wrong.
The hard part is finding a Rota-Derp dealer.
