This is wear from approximately 25,000 miles. The faces of the cam lobes are supposed to be surface hardened due to the constant sliding wear from the lifters.

And, uh, merkerguitars, it is a British bike. Many of the parts are interchangable with both Triumph and BSAs.

And just a little info for you younger guys and those of you just getting into doing your own wrenching.

There are no hydraulic lifters, I have to manually adjust the valves every 10,000 miles or so. I can actually tell how well things are running out on the highway from the noise made by the rocker arms contacting the valve stems.

No fuel injection, I have to tune the carbs every so often, I carry a small screwdriver just in case I need to touch up the carbs.

The cam drive chain has to be manually adjusted from time to time for the best performance.

The oil pump has to be taken apart on occasion and the sides honed flat to compensate for the wear of the pump gears.

It does have an aftermarket electronic ignition but that seems to have its own set of unusual problems and quirks.

This, like old Harleys, is a pre-unit machine. This means that the engine, primary drive, and transmission are three seperate units. The primary drive and final drive chains have to be adjusted together for smooth power transmission.

Oh, and it's kick start only.

Ya gotta love machinery to drive an old thing like this. Much of the technology in this 30 year old machine is from World War 2.

Next time some of you push the button on your modern, fuel injected, electronic ignition, bike from the space age and it starts right up and goes like a bat out of hell, give a thought to its ancestors.
