Fuel Injector Testing and Servicing

Improve performance, throttle response, drivability and economy from £15 per injector  

Fuel injectors should be regularly serviced! just like any other part of the motorcycle to ensure optimum performance. Even new injectors can produce less than perfect operation due to the anti-corrosion inhibitors used at manufacture.  This is particularly relevant if having your fuel injection re mapped.  HMR offer a service of testing and servicing for any petrol injector. 

Postal service available.
Matched sets of injectors supplied to race teams.

Custom Mapping

A custom mapping service, to get the best performance from your motorcycle and Power Commander costs £165 + VAT in most cases.

Dynamic mapping runs are carried out at full throttle, 80%, 60%, 40%, 20%, 10%, 5% and 2%.

These are augmented with steady-state tuning where beneficial for a perfect overall set up.

Dyno testing for Road or Trackday use

HMR offer the following rolling road dyno facilities:

Supply & fitting of Dynojet / K&N products

HMR will supply and fit Dynojet and K&N products. Dynojet kits cater for carburetted machines and Dynojet Power Commanders for fuel injected machines. See Dynojet for technical and application details.

Supply & fitting of Race Cans / Full Exhaust Systems

HMR will supply and fit race exhaust cans and full exhaust systems. After fitting, your motorcycle can be tested on the dyno and the air/fuel ratio checked and corrected if necessary.

Fuel Injection Re Mapping

HMR will optimise the fuel injection on your motorcycle via the fitting of a Dynojet Power Commander. See Dynojet for technical and application details. The Suzuki range of FI bikes can be re mapped using our Yoshimura facilities, providing a budget alternative.

Dyno Testing & Exhaust Gas Analysis (4 gas)

Our latest model Dynojet 250i Dynamometer is an essential piece of equipment for analysing engine performance. The latest real time air fuel ratio capability along with our four gas Sun machine allows us to analyse exhaust gases, enabling us to predict the correct jetting / mapping changes. The dyno is housed in a purpose built balanced cell, necessary for consistency of testing.  In fact the ventilation of our new cell provide a 'change of air' every 10 seconds!

Dyno testing for Race Bikes

HMR offers professional dyno testing facilities to race teams and individuals. Our latest model Dynojet 250i 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. HMR offers 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.

Carburation / Injection check £50 + VAT 

Professional dyno testing £50 + VAT per hour

Data Logging is priced subject to requirements
