You're worring about £4.50 difference, times a maximum eight, and you
won't need eight shims. Buy OE. It's safer.
What a total PITB that was but all 8 shims are now out. Yamaha wanted
£33+VAT for a removal tool but managed to fashion a bodge from an old C
spanner suitably butchered by angle grinder.
F knows how much this would've cost in a main dealer for labour alone;
screen, inds & fairing off, oil cooler off, carbs off, balance pipes off, do
shims, refit all, balance carbs
Noted your advice not to use pattern, what was the reason, are they not
hardened as good as OE stuff?
My next decision is whether to buy genuine Yam shims or to 'trim' the
original shims with my angle grinder....;)
Shims - I just don't see that the price difference justifies buying
pattern, and I'll tend to opt for OE parts where I can, but Olson
reports good things, and his judgement is always good.
Now - on reassembly, there's a really *really* important thing to beware
of (yes, I remember doing a valve job on my 900 Diversion). That's
refitting the oil cooler. You'll note there is a spanner flat (big
diameter) on each side, under the main moutning bolts.
You put an open-end spanner on each one as you torque down the mounting
bolts. They're there because if you don't, you can twist the casting as
the mounting bolt(s) tighten(s) down, and it cracks. New oil cooler
I saw them before I started the job. and asked my local dealer what they
were for, and he told me. So I'm telling you :-)
