Tuning & Dyno Centre
Offering a complete tuning service has always been BSD Performance’s goal and our fully equipped workshop, engine building room and Dyno all play a key part in producing reliable, rideable motorcycles, road or race, that are not only a vast improvement over stock but also live up to expectation.
We use a Dynojet 250i Load Control rolling road Dynomometer and the ability it gives, to control engine rpm at any throttle opening, is crucial for consistency and the precise build of a performance fuelling map. Ironically, the knowledge earned in the pre-fuel injection era, working on the Dyno with CV and flat slide carburettors has proved an invaluable foundation for everything we do with EFI.
With regards engine tuning the first thing we do is find out what the customer is using the bike for, and what they actually want to achieve by uprating their engine’s output. Using our experience we then establish the expectations relative to application; road riders and club racers have very different needs and this part of the process is, we feel, one of the most important.
Any motor that passes through our engine room is meticulously stripped, cleaned and, after the tuning work cleaned and patiently, methodically rebuilt. We take our time, and we take care.

2010 Triumph Sprint ECU Reprogram
The issues with this bike mainly concern power and power delivery off the bottom especially two-up. It’s been back to the dealer and had the latest factory tune, but the owner wants a little more. First job? Isolate the Lambda sensor and cap off the emissions unit. The bike was then put on the Dyno and we reprogrammed the stock ECU; fuelling at the bottom end has been richened up, taking away the ‘hunting’ snatchiness. Fuelling all the way through the rev range has been optimized and the ignition curve trimmed.

2009 Yamaha R1 Road to Race
To upgrade to race spec we’ve fitted an Öhlins rear shock and MCT have modded the front forks. The engine’s been out and we’ve adjusted the cam timing, ported and skimmed the cylinder head and we’re fitting a set of BSD Performance adjustable bellmouths. It’s also having a YEC race loom and ECU, plus quickshifter.
