To be honest, I don't really know - I did the whole "change lots of things at once" trick...
My gut feeling is that the headlight mounts, shock setting and triple clamp made the difference to the steering problem. The gearing, seat and footpegs are more about riding it faster, more comfortably.
Today, the new tyres and mousse tubes were fitted, along with that service I threatened (yes Ross, including lubing the chain). The top shock bearing is squeaking, so I've gotta lube that up, and I need to work out what they want me to do for mounting the number and make that happen.
