Dyno Services 
 
 JB Tuning are at the cutting edge of UK dyno testing and have been tuning and dyno-ing road and race engines 6 days a week, making us, some of the most expierienced dyno technicians in the u.k.

 

We have been at the heart of some of the best written and most read articles in sevral magazines, specialising in back to back testing and bolt on enhancements.

 

We are also one of the largest independant cylinder kit developers as well as working alongside 'replay scooters' to develop the agusto ignition.

 

 

 

The service that we can offer our customers:

 

Carburetor jetting,

Fault finding,

Ignition mapping/ general adjustments,

Cylinder developing and enhancing,

Exhaust manufacture,

Race preperation and development,

Transmition set up,

Real time gas analyzer.

 

 

 

 Jetting in your scooter or motorcycle using a lambda sensor:

 

 

 

      Lambda sensors produce a voltage signal that recognises the amount of unburned oxygen in the exhaust. An oxygen sensor is essentially a battery that generates its own voltage.    When hot (at least 250 °C), the zirconium dioxide element in the sensor’s tip produces a voltage that varies according to the amount of oxygen in the exhaust compared to the ambient oxygen level in the outside air. The greater the difference, the higher the sensor’s output voltage. The more fuel, the less oxygen. The more oxygen the less fuel.

 

     Using our dyno, we create a safe balance.

The Dynapro Machine:

 

Dyna pro Dynometers are a specialist company that design and manufacture their dynameters in the U.K. The business is a division of the John Dent engineering company, based in London.

 

Dyna Pro have made dyno’s for all different types of vehicles in motor sport, from F1 cars, to drag bikes. From mini moto’s, to go karts. Super bikes, and our very own race bikes as well as our huge list of previous customer ‘road going’ scooters. Be it a Vespa, Lambretta, or an automatic.

 

Basically, you have two types of user. One lot just want a power and torque figure, and then on the flip side of that, there are the high end tuners/ racers/ riders who want tons of other information.

 

What makes our dyno great, is how dynamic and adaptable it is. We can show you this information in our state of the art dyno workshop. For instance, distance over time, time over speed. And even engine efficiency.

 

 

The difference between our dyno and others in the business, is that out system takes the guesswork out of the performance equation.
