General Information

The process of Engine Overhauling is a maintenance type of job. The process involves the complete disassembly of the engine for inspection and the replacement of worn or damaged parts. Additionally, the grime and dirt will be removed during this process as well.

MotoGP Werks has been actively involved in road racing since the establishment of the company. During road races, the machines are required to run under high performance, therefore, the engine bears enormous load and is overhauled after every race. Engines of street use motorcycles do not bear such heavy load every time but there are different problems on Streetbike engines. Aging, the deterioration of each metal part, corrosion, sealing wear or soot from burning is seen in Streetbike engines that have not been maintained or serviced. A mis-conception about engines is that they are "maintenance free". We believe "Optimal Performance" can be achieved through a MotoGP Werks overhaul treatment and the learning of the "Environmental Conditions" that can affect the engine performance, is key to the longevity of the engine life.

MotoGP Werks role is to provide our professional knowledge and skills with appropriate prices to our customers. MotoGP Werks maintenance service has been improved and established over the years through working for the RedBull Yamaha, Yoshimura, Paris to Dakar 2003, John Britten, Kawasaki Factory Support Team and other regional championship road races. MotoGP Werks Engine Maintenance Service is always at your service.

 

Top End Service

Here we focus on the upper end of the engine, from the pistons on up through the cylinder head and cams. If you're looking at any of our cylinder head work, you may want to consider this service. It's a good place to start extracting even more power, the selected work is designed to complement and further optimize the potential of our cylinder heads. It's a nice upgrade from cylinder head work alone and will serve you well until you're ready or need step up to a complete build.

 

The Basics

Top end - teardown and detailed inspection
Replace - any / all necessary gaskets, seals, o-rings, etc.
Replace - any / all worn or marginal parts at or near service limit
Replace - piston rings and associated hardware (if needed)
Prepare / service - cylinders as needed (de-glaze/re-hone/re-bore/re-plate)
Prepare / service - all top end components and systems as needed
 

The Build

Top end - data collection, evaluation & development
Top end - integration of all planned work/components
Modify / optimize - piston crowns for increased combustion efficiency
Modify / optimize - piston skirts to reduce wear and friction
Plot / set - optimum deck height and compression ratio
Integrate / apply - optimum cylinder head work (see cylinder head development)
Evaluate / select - appropriate camshafts for application
Plot / set - optimum camshaft timing (degree cams)

 

OEM ENGINE RESTORATIONS

In addition to performance work, we provide standard engine rebuilding services. If you're simply looking to refresh or restore your engine to its original condition as delivered from the factory, we can rebuild your engine to OEM (original equipment manufacturer) specifications. Actually, your engine will be considerably better than what the factory provided - we have much higher quality control standards.
 

OEM - TOP END REBUILD*

Top end - teardown and detailed inspection
Top end - servicing/assembly as needed to OEM specs
Replace - any/all necessary gaskets, seals, o-rings, etc.
Replace - any/all worn or marginal parts at or near service limit
Service - cylinders as needed (de-glaze/re-hone/re-bore/re-plate)
Replace - piston rings and associated hardware
Refresh - stock valve job to OEM Specifications
Adjust - valve clearances
 

OEM - COMPLETE REBUILD

Complete - teardown and detailed inspection
Complete - servicing/assembly as needed to OEM specs
Replace - any/all necessary gaskets, seals, o-rinqs, etc.
Replace - any/all worn or marginal parts at or near service limit
Service - cylinders as needed (de-glaze/re-hone/re-bore/re-plate)
Replace - piston rings, main bearings & rod bearings
Refresh - stock valve job to oem specs
Adjust - valve clearances

 

COMPLETE ENGINE DEVELOPMENT

Here at MotoGP Werks we evaluate and develop the engine from top to bottom, this is the platform for producing power above and beyond that of just a top end service. It establishes a solid foundation for applying massive power increases. All of our racing and high performance engines are custom built. Below you'll find the general range of work for any given application. The full extent and specific details of your engine package will be determined, after an initial consultation. This service includes, but is not limited to the following:

* Engine designs that have the cylinders integrated with the upper crankcase as l-piece will require complete engine teardown for certain operations, such as: Cylinder block machining, if deck height can't be set with kit/custom head gaskets. Piston removal, piston ring replacement and/or piston skirt work. Additional Engine Services include; cylinder de-glazing, honing, boring and/or re-plating.
