ok, so i checked the clearances on my valves for my 1998 yz400. i was curious.... i noticed the dealer only carries shims/pads in .05mm increments, as well as aftermarket brands. i checked bikebandit, ronayers, TT store....all were .05mm. now, when i checked the pads that were in there, they were in .01mm increments. for instance i had a 176, 174, 180 pad in there. so by my super-power deductive reasoning, is it possible that these are the original pads from factory assembly? the kid i bought the bike from a few years ago said that he had the valves checked and they were good and no shimming was done. i just find it hard to believe that after 9 years, they are still in spec. if so, good job Yami!!!! :lol: any ideas?
