Motorcycle Dyno Tuning Services in Bristol

JHS Racing provide a comprehensive motorcycle engine performance dyno tuning & diagnostic service using our Dynojet rolling road facility.

We are an approved and fully authorised Dynojet Power Commander motorcycle dyno tuning centre serving Bristol and the south west. Our technicians are fully trained and certified by Dynojet UK.

Using the most up to date Dynojet 250i dyno in our air-conditioned facility we can dyno test motorbikes up to 500bhp.

In combination with the very latest tuning link software we can supply and install the Dynojet Power Commander or the Bazzaz engine management, quickshift and traction control unit, for any motorcycle. These units enable us to accurately set up the fuelling and ignition to achieve optimum performance. We also offer a procedure that enables making mapping adjustments directly into the ECU.

Direct ECU fuel mapping/re-flashing now available from 349, no need to purchase any additional fuelling module call us for more information
