Kawasaki Concours C14 1400GTR Valve Check Part 2.3 - confirmed gaps, next up is cam removal and shim measuring

I was busy at work with conferences, but got back for a Sunday afternoon in the garage. I'm trying out a new kerosene heater that seems to have solved my cold weather issues.

Once I had it into double digits Celsius I finished multi-checking the gaps:


Confirming the first round of measurements:

SPEC: exhaust valves 0.19 - 0.24mm     Intake valves 0.12mm to 0.17mm.

red = tight, white = spec, pink = on the cusp of tight: 

              Cyl 1                          Cyl 2                          Cyl 3                         Cyl 4

    EX  0.18   0.18               0.2    0.19                   0.19    0.19                0.19   0.21

    IN   0.15   0.14               0.13    0.13                  0.10   0.13                 0.11   0.12


Things are pretty tight. CoG has good resources on shim details. Tomorrow the cams come out, I measure what shims I've got, do some maths and order new shims for the tight valves. This means that perhaps next weekend I can turn a corner and actually start putting this thing (which is looking like a disassembled Concorde) back together again!

Unfortunately, I'm doing this just in time for the Americans to turn on us for no reason and make everything more expensive. Putin must be loving this, but then he did pay for it... but I digress.

Hopefully I'll have some time tomorrow to take out the cams and measure the shims in my warmer garage.
