Best performance mods!
I've had my bike for just less than a year now - 650 classic. I discovered the best performance mods which keeps the bike stock and cost nothing!
1. ear plugs
2. throw away the tach
3. adjust the head light
What a difference! Can't hear all the "whats that noise" stuff, shifting on feel instead of a number, and not afraid to drive at night anymore! Had to adjust the light way up - standard bulb.
