Today I checked the shim sizes in the Maxim X and instead of getting values in multiples of five, I have seven shims with number 188 and I have one shim with 192. One exhaust measures .20mm and the shim is 188. The valve clearance adjustment tool doesn't account for that number and it looks like it would come out to 183 So I'm not sure if I should go for 180 or 185. One intake measures .12mm and the shim is 188. That's close to the tight end of tolerance (.11 ~ .20) so I'd like to get more gap, closer to .20 What shim would I need? Another example is the intake measures .6mm but the shim is 188 so would I be best with a 175 or 180? I'd really like to get the values to be closer to the wide end of the normal limits. First time I've seen odd size shims.
