Just read a comparo on some 250 bikes, the Hyosung failed badly.

How's it been for you? I like the Misfit the most. I like them all though. And they are "local". I talked to the owner at the bike show last year.
Yeah the Misfit is cool too. I have had good luck with mine. I don't beat on it very hard though. I had Weaver Rides do some head work and put a different pipe on it, sounds great!! CCW is supposed to have an open house some time this summer, that I would like to go to.

The CCW have a good rep for a Chinese bike vendor. I like the cafe racer. I think my closest CCW dealer is 400 miles away in the DFW area.

Isn't that an ohc engine?

Nope, it's a one lobe cam pushrod. They were designed for the criminal abuse/negligence of SE Asia, so provided you change the oil and clean the filters (both of them, the spinner one can get filled up and it looks like metal when it's only compacted sludge), you have an engine that will last a long time. They do like it when you use the clutch to change gear though, they're not totally immune to brutality.

WOW! Thanks for the last diagram...that explains it best. What a step sideways in technology.

It's as old as engines, many manufacturers have used a single lobe cam down the years. It makes sense to reduce costly operations in manufacture, and grinding and hardening an expensive steel takes time=money. Ariel used it in their singles, I think even BSA at one time as well.

I found an even better demo: http://www.youtube.com/watch?v=TRKssCBrYxc
Honda were losing out on the SE Asian markets, because of the fragility and vulnerablility to zero care of their ohc engines. A working group from the factory went on a tour. On returning, the head of the group convened a meeting for the morning after the plane landed.
One of the engineers sat down and spent the night drawing up his idea for how a better suited engine should be built. This was fortunate for him, as it almost entirely coincided with the leader's concept.
They simply went back to basics and effectively created an upright version of the old C110/C210 engines. Pushrods, so reducing the amount of oil the head needed, and the cam down in the guts of the engine, swimming in oil. Further to that, changing worn parts is quick and easy, which is generally agreed to be better than scrapping an engine or complete bike.
