Zak125m

Hey thanks for looking at my thread, I just rebuilt my old 125m with new rings and gaskets due to blown head gasket, and its all done and put together and runs good now, has good power and doesn't spit or sputter or anything, idles and revs up fine too.
But it does make a noticeable amount of clatter from the head of the engine, I checked valve clearance at least 5 times and did it to the T according to the manual so then I checked the cam chain tension and that is good too, but it doesn't stop the clatter. I'm thinking it has to do with worn out springs or something to do with the valve mechanism itself, the valves are not leaking I checked that before I put it together so the valves seal fine and everything. Or is it possible its normal for the machine? Its not horribly loud but its not quiet either.
I am wondering if I can replace the springs, and all the other components in that line of things without actually removing the head, I don't want to take the valves out, just replace the springs and whatever else the rocker arm hits to push the valve open. Or maybe a solution as to why this thing is making what sounds like valve clatter? I used an automotive stethoscope and it sounds like it is coming right from under the valve covers.
