Boys don't powerwash your old bikes, you're gonna fok everything up.
I temporarily messed up my speedometer (condensation inside the housing), sidestand switch (engine shut down on me on a busy road last week -I later realized that the switch needed lubing) and brake lever (pressure washer unscrewed the screw that adjusts the free play)
That sidestand switch bug was kinda scary. I coulda died.
Bike looks clean as fok though.
