wont start, no spark

[sethacus]

so I had my bike parked for a couple days changed the front break pads and then it wouldn't start i played with it for 20 mins or so and then it started drove it around no problem. parked it the next morning wont start and that night looked at all of the electrical the spark was bad so went through the checks in the manual the ignition coil was not the greatest so i did the ford zx2 mod and it still wouldn't start then i checked the pick up coils (tested 107) and the relay assembly was good put it all back together tried to start it just for kicks and it started a couple times left it in the afternoon and then it wouldn't start in the evening again. any thoughts?

Put some new plugs in it. Charge the battery fully.

Try it and tell us what happened.

i put new plugs for a zx2 when i did the zx2 mod and i put it on charge and forgot about it but the battery is still decent but it helps to hook up the tender on 2amp. also got it to start and run without being hooked up on a tender.
