These pics are supposedly from a 2,000 mile inline four cylinder water cooled motorcycle engine.

The owner said he only rode it ten miles to work and ten miles back home for the entire 2,000 miles. I’ve seen completely worn out oil burners that looked better. Whaddyathink?

Every now and then a gasoline engine needs the flying snot run out of it. I rode dirt track scrambles for Triumph back in the 60s and 70s, had 4 Bonnevilles plus other machines and NEVER remember my engine guts looking like that. Carbon, yes - but those pics look "wet" - that engine is babied to death.

BUT - note the extremely clean piston rings and skirt - the valves are pristine - so the total performance loss is zero. 3 beerz and an afternoon of decarbonization and he's good to go.

I'm with Sub. That bike needs an Italian tune up. Of the dozen or so bikes I've owned, only one was water cooled but none of the pistons ever looked like that. My three favorite bikes were the BSA 650 upright twin, Suzuki GT 750 (water buffalo) and Yamaha Roadstar Silverado 98 ci v-twin. The only Harley I've had, I didn't have long because I didn't like it.

can't remember year model of my BSA, but I think a 1965. Loud, fast, awful Lucas electrics. But, in that day it was bigger than anything Honda had.
