I've got some tight valves in my 04 WR450F that need re-shimming. I'm going to order up a few different sizes of shims to make sure that I have the right shims when I take my cams out for the first time. What I'm wondering is if all (04)WR450's come stock with roughly the same stock shim size? I'm assuming that both intake and exhaust come with approximately 175 (1.75 mm) shims? Is it OK to assume that my stock shims are within .05mm of that size and order up the next few smaller sizes (1.70mm, 1.65mm)? What shim sizes did you guys find in there when you adjusted them for the first time? BTW- I've been reading this forum for a while, thanks for all the tips.
