OK, I got a 03 yz ex cam to put in my 02 wr426. I would like to install and shim it without running to the Yamaha shop once I get the readings. I see hot cams have shim kits but I have no clue which set to order. Any idea which set would be best?? Also, I’ve read a few threads on this subject but the answers bounce back and forth. Can I install the cam with the timing mark lined up (wr timing?) or does it have to be installed one tooth counterclockwise (yz timing?)? BTW I just installed the Rekluse auto clutch, that thing is the nads!
