2009 Yamaha R1
Why’s it in?
Conversion from road bike to full race machine.
Our treatment
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.
The result…
As stock, on standard pipes, a good R1 puts out around 158-160bhp at the rear wheel. With all the work we’ll be looking for somewhere in the region of 184bhp when it’s done; by comparison a well-specced BSB R1 makes around 195bhp. As this customer is club racing – and wants his engine to last a season before refreshing – we’ve built in a margin of safety for reliability.
Bike File

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.
