When we got ours it had 14,000 miles on it. the valves needed to be adjusted at that time; they were all too tight. I believe this is the leading cause of valve breakage.

That said, it also needed a new chain, the old chain was badly out of adjustment, a new rear tire, new fork seals and new front brake pads.

Get tapered feeler gauges that are the minimum and maximum for each valve. Bend the last inch or so to a 30 degree angle. Make sure the minimum fits and the max doesn't, otherwise, adjust them or have them adjusted. Checking should take less than an hour start to finish.
