So this occurs mostly on the right side. That does tend to point to an oiling/cooling problem and of course a bad design for the valve itself, excluding muffed valve maintenance.
So, like DR. Farkoff said, keep the valves loose and above all keep the oil clean, clean clean .... if you have one of these. Park it on the centerstand for long periods too if you can ....
I know guys running older bikes are not always able to throw money at the bike they have. But, if the bike has high mileage, why not tear it down and get some better valves in there and clean out the oil passages, Back in the day we would also scuff up the cylinders and do some new rings and valve seals and guides. But these newer bikes tend to have special cylinders/coatings that negate the need to re-do the rings in a lot of cases ....
Back in the early 70s when honda came out with the line of 4 stroke dirt bikes that were street legal, the SL bikes, they also went with the overhead cam. I knew some enthusiasts and they said you had to keep the oil clean as clean is because the cams were just seated in the AL head. And they would be flopping around not long if you ran them with dirty oil. This is why the yamaha XT 500 was such a hit. The cam was seated in roller bearings as was the crank shaft as well. This made these completely bomb proof for the most part. everybody bought yammerhammers if they wanted a four stroke dual sport ...... lol
