Suzuki GSX-R1000K8 Power Commander PC V fit and Dyno setup
This Suzuki GSX-R1000 is a nice example of the breed, fitted with Arrow cans. As usual with Suzukis it’s an easy bike to work on, and with, and the fuelling was fine after we’d set the PC V up on the Dyno. The real issue with this particular model GSX-R is the twin cans, and thus 4-1-2 exhaust; quite simply, it doesn’t work very well, and the left-hand can is pretty much there for show.
A full 4-2-1 exhaust system would work best for the engine, but for racing purposes (any class with a ‘silhouette’ rule) twin can must be used as per the stock bike. The problem seems to be removing back pressure from the 4-1 section – a flat spot follows around 5,000rpm. The ECU is also quite restrictive around that area, which doesn’t help.
All round though, this bike turned out well, and left with 168bhp, up 5bhp.

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.
