HELP! bike wont start! (electrical?)

[stirlinggaz]

hi all,
went to start the bike (aprilia rs125) this morning for the daily commute & nothing happened!
pressed start button but all i could hear was the relay clicking!
so knowing nothing about electrics, i jumped straight in & started ripping the bike apart!
anyway heres how far ive got:
took the starter motor off, stripped it down & cleaned it all up.
wired it up to 12v supply & it whirrs away quite happily.
so its not the starter motor, (phew, they are about 70 quid)
must be the relay, right? (thats ok, they are only 20 quid)
well i have connected up everything loosely, & when i press the start button while holding (not directly, dont want shocked!)
the motor against the engine casing (to earth it?)
the motor whirrs away, but not if i put the motor back in where it came from?
so does this suggest something is not connected up properly?
im thinking its not "earthing" as it should.
so how would i go about earthing it?
i have checked all the wires & they all look ok.
any ideas/suggestions welcomed,
as its the bus till its fixed!
cheers,
GAZ

Have you checked your battery isnt dead? when mines been run down, it still clicks but doesnt start.

{edit} check your killswitch isnt on too

sorry just re read your post properly, if your relay is clicking i doubt it will be that, youve already ruled out the starter motor. I'd probably put it down to dodgy wiring.

In gear maybe? Wont start when in gear and sidestand is down.

Double check its not in gear, and try it with sidestand up...

The fact the relay is clicking makes it sound like the battery is flat... i know youve said its charged but do you have another you could try on it, or a booster pack etc.
