This Suzuki GSX-R1000K8, fitted with Suzuki’s own GP Evo cans, came in low on power; it was making 159bhp and the fuelling was all over the place. We supplied and fitted a Power Commander PC V and on the Dyno it was measurably and noticeably ‘woolly’ at the bottom end; too much fuel was going in, so we took some out. In the upper mid-range and at the top-end it was lean, so needed more fuel. It rolled off the Dyno for its roadtest with a much-more-like-it 167bhp at the rear wheel.
Which is when we found another small issue with this particular bike – it didn’t feel good out on the road. The owner hadn’t touched the suspension, but wasn’t over keen on the Michelin tyres it was wearing and was planning to change them, so we had a close look at the settings on the front forks and rear shock and found, much like the fuelling, they were all over the place. We simply measured and set-up the static sag, took out a touch of rebound, and it was transformed.
