My old CBR1000 uses threaded adjusters, but I'm sure that the 954 uses shims. Basically, you have to measure each of the 16 valve clearances and write them down. If any have to be changed, you have to remove the cams and insert a larger or smaller shim under the bucket to lower or raise the clearance. You take out the old shim, read the shim thickness, or if it was inserted upside down, you will have to measure it with a mike. Then you have to go to the dealer and see if they have the shim(s) you need. Then the cams have to be put back. It's actually a lot more involved, and you need the manual.
