We’re seeing more and more of these – GSX-R1000K1 to K8, and all models in between – wear the selector fork on the input shaft into the gearbox. Once that starts to wear it won’t select third and fourth gear properly, chews the end off the corners of the dogs and then won’t stay in gear. The only solution is to pull the engine out, turn it upside down, strip out the worn parts and replace (usually three gears and a selector fork which come at around £350) and put it all back together again. That’s a minimum of eight hours’ workshop time plus the bits but the only solution. So if your GSX-R is having gearbox issues you know what’s what – and you’re not alone…
Major surgery is required to replace three gears and a selector fork...
