Dyno Testing for Race Engines

We offer professional dyno testing facilities to race teams and individuals. Our latest model Dynojet 250 dynamometer is housed in a balanced cell for accuracy and consistency. Along with Dynojet's real time air/fuel ratio capability, we employ a 4 gas Sun machine to analyse exhaust gases.

We offer data logging facilities to record conditions and results obtained in the dyno cell. The data acquisition facility can be expanded to use on the track for the professional client.

Data Logging is priced subject to requirements.

Racing Suspension Services

Basic Service consists mainly of changing fluids and inspecting all parts (bushings, seals, wipers, o-rings, washers, etc.) for wear and damage. Forks and shocks are completely disassembled using the proper techniques and tools, cleaned, and are reassembled with fresh oil and nitrogen (for shocks). Under average use conditions, we recommend suspension service at regular intervals (at least once a season).

A Rebuild is essentially the same as a service, except that all major wear parts are replaced (seals, scrapers, seal heads, bushings, etc.).

A Revalve is our most specialized service, and includes everything done during a routine service, plus the reworking of the internal valving system within the fork or shock. On damper rod forks (older style conventional forks), the existing holes in the damper tubes are brazed up and different holes (diameters and locations) are drilled. Depending on the rider and application, cartridge emulators may be added. On shocks and cartridge forks, washer stacks are removed from the valve assembly and are modified using a computer modeling program. In conjunction with our experience and knowledge, valve assemblies are restacked in order to achieve characteristics to better suit your needs and make your bike work better for you. In conjunction with all revalve work, springs may need to be replaced or modified, depending on the bike, rider and application.

Field and Race Support is offered for road and dirt bikes. We spend much time at road race tracks and popular dirt riding areas . We can help make your track tuning time more valuable by providing on-site feedback.

Swingarm and Link Service should be performed on dirt bikes at least once a season if the bike is used regularly. This service consists of removing the shock, the link assembly, and the swingarm if necessary, and lubricating the needle bearings with grease and cleaning the seals and inspecting for wear and damage. A regularly serviced swingarm and link assembly can last several seasons, even when ridden in extreme conditions. When left un-serviced, handling and suspension problems often develop due to either play in bearings or frozen links, swingarms, and axles.

Headset Service is less of a concern, but periodically needs maintenance like the swingarm and link bearings. We routinely install zerk fittings into steering stems - so in the future the headset can be serviced at home with a grease gun.

Other general services include wheel bearing replacement, basic welding (steel or aluminum), minor pipe repair, fork tube straightening, limited machine work, shock heim joint replacement, and other services. Just call and ask - and if we can’t help you we can probably tell you who can.

We have the specialized tools and knowledge to work on all types of suspension, whether it be KTM PDS shocks, Ohlins forks and shocks, or Honda twin chamber USD forks. We regularly spends time riding many of customers’ bikes making sure that we are indeed getting the results you are looking for.
