Bike won't start - help!

[JustcallmeMrT]

Well gents, after a blissful week of riding, my bike no longer starts, and I can't figure out why for the life of me.
It became harder to start over the course of a few days, but now refuses to catch at all. 

I have done the following:
-checked valve clearances
-checked static timing
-cleaned and gapped the points
-replaced condensers and spark plugs - spark seems ok
-checked function of coils - all values fall within normal ranges
-replaced battery
-checked frame grounding points for corrosion, found none.
-sprayed easy start directly into the intakes, no go.

What could it be?  I'm all out of ideas.

if you have sparks,and compression,

 make sure you have plenty of fresh petrol,

Not sure on the compression, trying to borrow a gauge to test.  Fuel is fresh.

Yep, definitely flowing.

Blocked air flow/filter?

Blocked air flow/filter?

New K&N filters, only 200 miles on the bike since it was dyno tuned to suit them and the new exhaust.

If it will not fire on easy start, I would assume (without seeing the bike) that it must be a firing problem. When I come across this in the workshop, I would try to bump start the bike and if it would not fire on easy start with a bump I would always be back to the drawing board while a lot of head scratching went on.

Will try a bump start then!

It is very hard to comment when a bike is not in front of you.

I know.  If I had a van I'd bring it by.

Try turning it over with choke fully on first then remove choke and hold throttle wide open to see if you get any response at all, if it doesn't fire it should probably at least give you a cough or maybe a backfire. You can do this either on the starter or by bumping it.

Mr T. Not a lot of help today, as going away. But am only just down the road in Maidenhead. PM me if you like and we can compare notes etc. Back 9th.

After you've tried starting it are the plugs wet (possibly implying unburnt fuel, no spark) or dry (possibly implying no fuel)?

The plugs are wet after starting, but seem to have spark?
