How to check the spark

[Tiger-ish]

Hello all:
New to me a triumph tiger 2006 955i.
It has been sitting for several years, but was stored inside and appears to be in good shape. I have pulled off fuel cell and air box.
Q1 :What is the easiest way to check for spark on these units?
Q2: new battery and it does turn over, but starter will not engage unless clutch is engaged, even when in neutral. Is this normal? Every other bike I had you can start in neutral with no clutch.
Thank you for your help.
I'm sure I will have further questions.
