Message from Rick Brake of RBmods.net :

History and the making of a new STS MK11 engine. When testing the D21B and D21T engines my preliminary diagnosis led me to study these engines in depth and have my drivers testing them.

Everything I thought the engine would do was correct, These were great engines for the price but I thought STS could do a little better with the same amount of effort. So after a few emails and sending them pictures on what to do if I were them they came out with a engine after my own spec’s. They actually produced a great engine that would give these 400.00 and 500.00 dollar
engines a run for their money. This was dubbed STS MK11. My drivers have been testing it and found that it was able to keep up and even surpass these high dollar Italian engine with the grace of a expensive .21 5 to 8 port engines and get about 9 minutes of run time doing it.

As I watched the testing this engine had taken a buggy and was pulling wheelies up to 75ft down the straights with a crisp sound that I and you and everyone else likes to hear at 202 degree temps. I had thought that it was time STS release these to the market to compete against the ever soaring over priced Italian engines.

Finally! You to can have this engine and feel the bliss of knowing you got way more then you paid for and probably for the first time. These engines are worth every penny. Modified they are off the hook, Smooth, powerful, reliable.

Extreme Engine Mod by Rick Brake of RBmods.net

Here’s just a few details of what you get with this mod:

1) A High Efficient mod with timing and firing pattern’s re-established.

2) Crank boring, induction ports sharpened.

3) Sleeve sculptured to maintain velocity produced by crank at lower RPM throughout the power band.

4) Crank is cut for turbo charging the fuel/air mix.

5) Pressure release cuts made for an easier transitioning between power stroke and exhaust stroke.

6) RBmods replaces the factory front engine bearing with a special high precision bearing to handle the added RPM from the mod.

7) ***NEW** RBmods goes above and beyond… Crank Hardening and Rust Proofing.
A reverse osmosis procedure bringing you the best of all the other mods out on the market, Yes sir we have come full circle with this
one folks. Just take a look at the picture attached Notice how some engines loose power and start acting up after some of the
nasty fuels we use? It is the crank rusting up and sending rust particles through your engine, Of coarse you know this would have a adverse affect we all do not want. Dr. Rick has come up with the cure and better yet without raising the prices.

Enjoy and have a great day. Rick RBMods

Many other things are done to the engine but RBmods can not give all their secrets ;0)
