Received my box of shims yesterday + a new set of feeler gauges
just need to pluck up the courage now to get stuck in and get them done :-) before the weather turns

But it has been so nice that all I have been doing is going out for a scoot every evening :-)
and the weekends are spent out scooting in the countryside early before the plague of cyclists get out

Well eventually got around to doing the shims
took off all the bits on Wed afternoon as I had some time off

5 valves in total that were out of spec  2 in and 3 exh   
I tackled the measuring and shimming on Thursday ( Thanks Towerman for the shim calculator xcel sheet came in very handy :-) )

To my surprise the shims were not the stock 2.95  couple of the exhaust valve shime were 3.15 so maybe it did get some Tlc along the way :-)

Also In my bid to track down the dreaded 3000 rpm buzz I removed every piece of plastic up front looking for what ever it is that's causing the noise
So now I don't have the buzz at 3k rpm any more i have it at all revs :-(
I did pack in some foam draught excluder about the headlight area where some folks reckon the noise comes from
Sounds like it is coming from the front end alright but despite riding along and trying to find the offending vibration I have had no luck

So maybe the next step is to remove everything but the headlight and drive up the road and see if the noise is still there
Then start adding 1 piece back at a time till I get to the bit that's noisy

 My '014 came from factory with 300 shims across the board.

 Better earplugs and ignoring it is the most effective way to deal with the buzz. It comes and goes at random. Even ambient temperature can make a difference.

Better ear plugs are on the way
But i seem to have made it worse by taking every last piece of plastic up front thinking that I might stumble upon something loose ( no such luck ) :019:

 The buzz seems to be more a combination of harmonics resulting from fastener  torque plus a few daily variables rather than loose flappy bits.

Hopefully the new earplugs will drown it out :-)

That IS surprising, you would expect them to be smaller, not larger ...

Also the factory ones have no numbers printed on them - mine were all ~2.95 when I measured them with a micrometer and the bike had about 55k on it when I did them. Most were tight.

Yeah they were after market ones as the number was printed on them
And as you said you would have expected them to be smaller to allow for wear not bigger
But all is well that ends well now it is done I can cross it off my list 

But on a positive note
My heated grips arrived in the post as did my topbox and mounting kit  a Shad 40L cargo  and a bag of 50 pairs of earplugs 

Just maybe look at some new tyres now
i can tell when a car tyre needs to be replaced but a motorbike tyre is a different story

This is getting to be an expensive hobby :-)

 "This is getting to be an expensive hobby :-)"

 Yup. When all said and done a Honda Fit (Jazz) or similar is cheaper to run than a V 650.

 There is no longer the excuse of owning a bike as an economy measure, even when you do your own maintenance. Sad but true.

 The modern version is something along the lines of "For my mental health, Dear. I need it". Just don't let 'Dear' near the forum because she'll quickly realise we're all nutters anyway  :124:

Rob its definitely good for the mental health :-) to be able to just get out there :152:

I can also convince her that it is cheaper to run than the car ( had to replace the steering rack on the polo ) ouch
