The KL250 is back

The KL250 finally came home after six months in the shop. I had sent it in for an overflowing carburetor.

The wait was almost entirely because the parts do not exist. I do not know the exact year, but the bike is probably about thirty years old. With nothing in the catalog, the shop gathered whatever looked like it might fit, and that is how it got fixed.
It used to shudder in a certain rev range on a steady throttle. That is gone. The engine feels fuller everywhere, and the bike is simply more fun than it was.
I will use it around town until I am used to it, then take it a bit farther.
While it was there I asked whether modern fuel-injected bikes break too. They do, just differently. The trouble is that the cause often cannot be found, so the usual repair is to replace the whole unit. That is exactly why I have stayed away from fuel injection. Hearing it from the shop floor confirmed what I already suspected.
I know machines fail. What I cannot get used to is the modern habit, from computers to phones, of throwing the whole thing away. I understand that hunting one failed part inside a complicated computer costs more than fitting a new assembly. "We don't know why, so scrap it and buy another" still feels like a sloppy way to think.
This motorcycle is more than forty years old, and with metal and rubber parts replaced it still runs with plenty of life.
