Interesting engine failure
Engine pictured is a Honda CX500 motor. Bulletproof engines, they'll run forever. Anyone ever seen an engine fail in this manner? What could cause it?
2000 CR250, pipe, filter, Vforce
1980 XL80s
1969 Broncco TX-6
Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.

The failure isnt the sleeve, its the aluminum jacket holding the sleeve.
If it detonated really hard, and either lifted the head right there or dislodged the gasket, the pressure would be directed right at the aluminum jacket.
If coolant got into the cylinder and you hit the starter button, it might have done the same thing.
What does the H/G look like? Do you still have it.
Was it running when it happened, or did it run fine, was parked... and then ran like shit on the restart?

Use an end mill and plunge into the side of the sleeve and the water jacket casing only enough to retail an aluminum dowell, it's the same thing we do with the Honda car blocks that aren't running darton sleeve packs. I'll post pics in a dew days

So youre saying the motor is possibly saveable?Roostius_Maximus wrote:Use an end mill and plunge into the side of the sleeve and the water jacket casing only enough to retail an aluminum dowell, it's the same thing we do with the Honda car blocks that aren't running darton sleeve packs.

Dont know. A guy on another forum bought the bike knowing it had a bad motor. The discussion is speculation, mostly. The P/O said that it began to run really weak.AlisoBob wrote:The failure isnt the sleeve, its the aluminum jacket holding the sleeve.

I mainly posted this as just something that I thought intriguing, in the hopes of learning something

in these pics you can see where the honda blocks with the floating sleeve like that one are cut down and a replacement with support is added.
It wouldn't need to be their sleeve, but the same idea
