hensim valve noise
i recently picked up a hensim 250cc dual sport. it runs like a champ minus some noisy valves. attached is a video, is this normal? i know there are some threads on here that say noisy valves are just part of the china bike sound

Welcome; we are glad you joined us.
 If you just acquired the bike, I suggest you check the valve lash; it's not a difficult job.  http://www.chinariders.net/showthread.php?t=977

Welcome, PNW'er! I live about 45 minutes North of Bellingham. You live in a beautiful area.
Spud is right, as usual. Setting valves is not difficult. You have the coveted OHC version of the Honda clones.

@fastrs2.5
Sounds very loud. Does it still have the air filter box? @Spudrider THanks for bringing that link up. I might try that one of these days. Too bad the pics are gone.

If the valves were really noisy before, they were too loose. Adjusting them properly would give you a little more power, and probably easier starting.
