REVTECH ENGINE

NEW REV TECH 4 BY 4 ENGINE-- The engineers and technicians at RevTechÆ went back to the drawing board to create our next generation 100-inch engine. We studied the latest technology, combined that with expertise gained on the first RevTech, 100 project, and got down to the task at hand. The goal was simple; create the best all-around engine for the American V-Twin market!

Fortunately the RevTech design staff did not have to start from scratch.

We began with a solid foundation, the fire breathing RevTech 110 power plant, and refined it further to produce a motor for most everyone. By shortening the stroke to 4-inches, excellent balance with less vibration was achieved. A positive side-effect of the shorter stroke was reduced piston speed which increases reliability due to lowered stresses.

Components

The 4 pistons pushed on these 4 strokes are a special story in themselves. RevTech worked with Wossner to design unique moly-coated forged pistons specifically for our engines. If you're not familiar with Wossner, here's a bit of background: They manufacture pistons for a little company called Porsche, among others!

Next we redesigned the heads. The bigger bore of the new 100 allowed the use of larger valves, so the ports were also redesigned for better flow. Smaller combustion chambers provide greater squish area for better turbulence and efficiency. In addition, roller rockers are employed for better valve train reliability.

Many of the fine features of the RevTech 110 were retained due to their proven success. Pressed-together flywheels and our industry-first monoblock crankcases are still used for excellent reliability. Blind case bolts, machined fin edges, and John Reed design rocker boxes, follow the RevTech tradition of making it work well and look good. Plus loads of horsepower and torque for all types of riding come standard.

So did we reach our goal of the best all-around engine on the market? We think we did and believe you'll agree. Remember, there are millions of American V-Twin motorcycles on the road today; why not make yours perform like one-in-a-million?

I Recently purchased a 100 inch rev tech. There is no comparison to any other V~Twin. It has Raw Power. After riding many Evo and Shovelhead motors. The 100-inch by far blows them away.

I Recently took a ride on a friend's new bike and was blown away that I thought his Harley's power was no match for my Rev Tech. I actually thought there was something wrong with his new bike, my Rev Tech has power and torch from Hell. She comes alive from jump street.

I'm so impressed with the 100-inch that I'm building another bike and it also will have a Rev Tech motor. I'm wondering why I never purchased this engine a long time ago. The performance is unbelievable. Thank you Rev Tech for the ride of a lifetime. I've never had any issues with my Rev Tech motor. I'm RedBone and I approve this motor..see y'all on the streets...

Editor Response From Custom Chrome. We used a Rev Tech motor in our Shrunken FXR. We have never had any issues.

please send the newest catalog available.
I have a 100 inch rev tech motor in my 2003 Independence Freedom Express and have had so many problems with this bike and motor not sure if it is the bike or the cycle shops in the Richmond, VA area do not have to work on bikers or are purposely sabotaging my bike.

Please, I need a new motor or some one who knows how to fix mine. Have spent over 10k in repair shops and it still does not start right and leaks black oil above the oil filter, bell housing, stator set screw missing and fluid leaking on rear drive belt.

TOO MANY PROBLEMS PLEASE HELP. 804-389-2994

Editor Response Have you tried Departure Bike Works. Lee and Brenda have been around for like 40 years. I will also ask Joey from Custom Chrome to drop you a note about your specific problem. Let us know what works out.

Actually a lot of Rev Tech engines were very tough engines and easy to work on.
