We will need all the parts that we are working on, which may include your cylinder, head, power valve, and piston. Also before sending your cylinder in, you need to either fill out our Service Order Form or e-mail email@example.com, or call us to have an estimate created to print and send in with your cylinder to
1404 Pilgrim Road
Plymouth, WI 53073.
Although, it is not mandatory, providing us with a new piston is always a good idea. By having a piston we can ensure proper finish bore size, as well as making sure that your new piston hasn’t been damaged. In most cases, we can do a cylinder to stock dimensions based on provided make, model, and year. If you would like us to provide a new aftermarket piston, simply choose the type you would like and indicate it on our Service Order Form and send it in with your cylinder.
You can send in just your cylinder, all components you want serviced, or even your entire engine for us to provide engine rebuilding services for you. We recommend calling one of our service technicians to discuss all options available for your specific needs. Millennium Technologies will not be held liable for any damaged or broken parts that may result from disassembly. This includes cylinder head bolts! Please remove them from the cylinder; we will not be liable for any damaged or broken head bolts. If removing a head bolt results in the need for a heli-coil, the customer will be contacted to be notified of the additional costs.
No, we recommend that you send the entire power valve assembly along with your cylinder and take advantage of our power valve service
Yes, we often will purchase your used cylinders without requiring any purchase or exchange with us, but it depends on your specific cylinder and the condition it is in. Feel free to call us to discuss selling us your used cylinder(s).
We do sell cylinders outright depending on inventory levels and availability.
We carry over 10,000 cylinders in our core inventory to fit almost any application. We recommend calling one of our sales technicians to discuss all options available for your specific core needs.
Typical turn around times are 5-7 business days for single cylinder and head services, 7-10 business days for mono blocks, inlines, and integral top cases, 14-21 business days on automotive and engine building services.
There are always many repair or modifications options for your cylinder, please call one of our sales technicians to discuss what range of options and pricing are available for your needs.
Overbore or oversizing options vary by model and application. We recommend calling one of our sales technicians to discuss all options available for your specific needs.
When doing may big bore kits, it is necessary to modify other parts of the motor. Often times, the power valve assembly and/or cylinder head require changes to accept your new bore size. Failure to modify these parts will result in power loss and/or engine failure. If you are unsure of your needs please contact us.
Your cylinder should be bored to .007” (±.001”) over your finish bore size. In other words, take your piston size, add clearance, and then add .007”. When doing your final pass, it is a good idea to use a new bit to ensure we receive a smooth, groove free surface that is ready for plating. If left undersized or too rough we will need to re-bore your cylinder, negating your attempt to save cost and time. Please do not hone your cylinders at this point. Honing on bare aluminum forces oil into the casting and can result in excessive porosity.
Porosity is gas trapped in the base metal aluminum during casting. These “holes” are exposed when the cylinder is machined or subjected to various chemicals in the plating process. The pits are usually small in size, and in good castings few and far between. When kept under acceptable levels, porosity will not adversely affect the performance or longevity of the engine. In fact, it will improve lubrication. The pits will not cause the coating to peel, nor will a ring hook on them. As far as our specifications on porosity our cylinders carry a lifetime warranty against defects in materials and workmanship. Therefore, through extensive testing we have found that porosity is a cosmetic problem only. In our pursuit to have both cosmetic and functional perfection we do everything possible to remove these pits. In some cases, this is not possible, so we release the cylinder only in cases where it will not affect performance.
Oleofilic is a natural tendency to absorb oil. Coatings that are oleofilic help the oil retention of the coating and reduces the wear on the surface.
Please see our jetting guidelines.
In most cases, your cylinder was not designed to run with an iron liner. Installing a sleeve not only adds weight to your cylinder, increases operating temperatures, but you will also be sacrificing the unbeatable wear characteristics of an NSC coating. An iron liner will wear 10 times faster than a plated cylinder, resulting in too much piston to wall clearance. Which can result in engine failures. In addition, re-plating your cylinder with NSC will almost always be less expensive and less time consuming.
We can plate many materials, cast iron included. By plating cast iron the cylinder will have all the benefits of NSC except the heat transfer. These benefits include 10 times better wear resistance, more horsepower, and better ring seal.
We offer many porting options for two and four stroke applications. We recommend calling one of our sales technicians to discuss all options available for your specific needs.

Revolution Performance bores cases according to cylinder manufacturer’s tolerances. We have a detailed process for each manufacturer and may choose to position center case bolt as a "through bolt "versus a "tapped blind hole" for added structural integrity. The positioning of this bolt is critical and must align with case opening so it does not damage cylinders upon installation. Weeping at center case bolt may occur if not sealed properly.
All specifications for our work meet or exceed OEM specifications.
Our crankshafts will install as any stock flywheel per the manufacturer’s recommendations. We hold strict tolerances according to or exceeding manufacturer’s recommendations.
