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.

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.

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.
