“We’ve got a mix of road riders coming out of hibernation and racers desperate to get out on track with their new bike. So it’s set-up and engine tuning at the moment.
“We had a Suzuki SV650 in the other day that looked the part, but the handling was terrible. Like a lot of owners the guy had thrown in suspension from a ZX-6R, ZX-10 or GSX-R because it fitted. But the spring rates were all to pot. He’d have been better looking at a £400 Nitron shock, new fork springs and emulators.
“Re-flashing ECUS has been getting bigger and bigger as modern bikes are running so lean for ride-by emissions tests. Late ’90s and early 2000s ECUS are very basic, but on more modern ones we can adjust ignition, fuel and throttle plate positioning. Although you’ll see a 5-12bhp peak increase on a big bike, the real benefit is in the second-to-fourth gear range.
“A reflash will take a good four hours, taking fuel out of some cell blocks and adding it to others before each dyno run. On road bikes we are looking at small and midthrottle positions where you spend most of the time – you’ll only be using 10-20% throttle on the motorway. We recently reflashed a GSX-R1000 K5 with an Akrapovic pipe and it gave 12bhp more in second and third, making it nice and progressive on the throttle.”
