I took the cover off the cams to adjust the timing to a yz set up and I noticed that on the top of each cam bearing tower there is the number 21 hand scribed into each tower. The timing doesent look like its been adjusted yet but are there aftermarket cams on my bike? :applause: Does this "21" mean anything to anyone. Just want to find out before I go ahead and adjust the timing. Thanks. :bonk:

If the cams look like yam ones ...with the pressed on wheels, and no adjustment ...then there probably standard ones :applause:

what is the setup to convert a WR to YZ timing? Is it the same a the YFZ, move the exhaust cam 1 tooth back? :applause:
