RD 400 melt down

I hear that a two-stroke is more susceptible to ignition timing and fuel issues than a four-stroke.

The owner says “by the time I realized the improper fuel/ignition, I just decided to push it.”

If you ever see these guys getting anywhere near your motorcycle, run the other direction.

Halloween 2005
This is one of two heads off a Honda CX 500. All I know is that the engine was being run at high RPM and it dropped a valve. Unfortunately, this is the only clear picture of the bunch that were taken.

The cobwebs are not normally present in a running engine. I suspect this head was sitting on the floor in a garage for a really long time, just waiting for its day on the Internet.
These pictures are from a Shovelhead of unknown year. It’s a custom bike with a blower on it. We suspect the bearing supporting the end of the pinion shaft extension had too much clearance, and the bottom end starved for oil due to the excessive clearance.

This was a fresh motor with around 100 miles on the rebuild. The next rebuild is going to be really expensive.

This is the cylinder head from a Honda CB 160. Unless you know what you’re looking at here, it won’t make much sense. In the picture, the valve adjuster is visible off to the side because it broke off the rocker arm. Cool.
