Bike was running. Now won't start.

Had that the other day on a Triumph, lovely spark but, no spark under compression.

I will look into the possibility of no spark under compression. I still have the old coils. I'll put them back on and see what happens.
dbscots:
Okay, I swapped the gl1000 coils for the stock ones and there was no difference To tell you the truth, I've never heard of the concept of plugs not firing under compression. You learn something new every day. So, assuming it's not the ignition system, what else could make a bike that was running pretty nicely suddenly quit and then just not start again?

A triumph! Never trig
Chris400F:
As Bryanj has already pointed out, lack of fuel in the correct proportion (or a total lack of) will mean the engine will not run.
You say you have a tank full of fresh gas, is it getting anywhere?
Can't see any mention of this having been checked.
Is there possibly a blockage in the fuel tap or the pipe between tap and carbs?
