Both he Yamaha service and Haynes manual are both confusing because in one place it says 0.25 and another it say 0.30. :'(
The early 98 R1 service manual say 0.21- 0.30 and the EXUP service manual is the same
I rang Yamaha Ireland (did not really believe them) and also rang Yamaha UK and both said the FZS1000 are 0.21 - 0.30 ex :eek
When told this I checked with a few different mechanics and all said the same, early R1s and Fazer 1000 5 valve heads are 0.21 - 0.30.
I have always set any 5 valve heads between 0.21 to 0.30, my own included without problems.
On the shim size, the nearest I have to 189 is a one marked 190, but measures between 190 and 191on the micrometer
Might write to Haynes out of curiosity :b
