I don't think that is your problem.  Did you recheck your valve adjustment the first couple times you rode the bike after installing the new cam?  When you install a new cam and do a top end, everything wears in the first couple times the engine is run and some of the clearance in your adjustment may be taken up.  If the engine is allowed to run for even a short period of time with no valve clearance, then you will score your cam.  If you have no clearance, it squeezes the oil out from between the cam and the rocker arm and gives you metal to metal contact.  This is usually what causes scoring or galling of the camshaft.

Does the cam or rocker arm show any indication of heat.  Discoloring or blue color?  If so, this may be what happened.

Camshaft break-in is very important also.   When installing a new cam you should run the engine on initial start up at a fairly high rpm for about 15 to 20 minutes.  Many cam grinders recommend this proceedure.  After this is done, you should let the engine cool down and re-check your valve clearance.

Also, those little wave washers on the rocker arms can be replaced with flat washers.  Just be sure to leave enough side thrust clearance so that the rocker does not bind in any way.

Just my $ .02  Good luck. :thumb:
