I walked in last week and Chip had this 510 up and running. It seemed like he did it in 10 minutes, but that’s likely because he hadn’t mentioned it the last time I was there. The shell looks a little rough, but he’s replaced all kinds of suspension and mechanical goodies, so it started right up and ran like a top. Under the hood is a new master cylinder, new fuel pump, radiator, fuel filter, fuel line… I can’t remember everything.

Chip separates the collar from the tube so he can set the height where he wants it. I think he told me he cut the springs about a quarter of a coil, also, but check with him for the final figure if you’re thinking about it.
This all proves to me that you can’t leave a racer in the room alone with a 510. These kinds of things happen.
