I'm not shy at all about mods on my bike, it was far from original when I got it and already had one foot in the grave. That said, I agree about preserving the OEM parts which have managed to survive this long. I also try to keep true to the spirit of the original bike in my mods - I'm not trying to make it into a different bike, but personalizing what's already a great machine.
So, clipons, seat, and tank dents. All of those are reversable mods. Got anything else in mind? Any bikes you find particularly inspiring?
cheers
