Hi guys

Does anyone know how to reduce the tappet noise on this 200cc pushrod engine (can the engine make even be identified?) The factory clearance is supposedly 0.05mm intake and exhaust. But is this hot or cold? I tried it both ways. It still makes too much noise for my liking after just 5 minutes of riding from cold. I've even got it where there's practically no clearance on both valves when cold, and still it's noisy. This engine only has 1400km, or 870 miles on it. People say it should be a bit noisy, but how much is too much? Is there some trick with these pushrod engines?

Any help would be appreciated.
