Noisey Engines?
Hello everyone. Has anyone noticed that these Chinese engines seem to be a liitle more noisey than their Japan counterparts? I just got dont going through a Wilderness 250cc from front to rear, the absolute worst things is for these atv's to sit for a long time. I was just curious as to everyone elses thoughts on the engines.

I bought it used and sitting a long while. I now have it running excellent except there is valve train ticking that doesnt sound normal to me. I set the valves at 4mm perhaps they need to be a tad bit tighter. This one has me stumped because i cannot see anything that is out of the ordinary.

I guess the big question is that if the valves get to be too tight will they also tick? I guess its possible because they are working way to hard, after researching a bitI think that setting them at 4mm is indeed to tight, geez I wonder what I was thinking. Back to the drawing board I guess.

I agree. I will double check the settings but it starts right up and runs very good. Its just noisy in the valve area like one is loose, but based on what I am reading its not possible. I set them to .004 but the service manual I found calls for .005 intake and .009 exhaust. So I am clearly tighter than what it calls for yet the noise it makes sounds like its loose . Thats why I was asking if a tight valve also makes a ticking noise similar to a loose one but not as loud.
