Electrical

right lets get a brainstorm, charger shows battery full, but wont start on the button, and datatool alarm triggers everytime it tries to arm

no indicators connected but was working fine before with them off

check your alarm fuse, normally 10amp. Failing that put a multimeter across the battery to see what you are getting then press start, if it goes to 0 then good chance bat could have a cell gone down. See if you have a friend who will let you try their battery in place of yours for conformation. Apart from that you could have water corrosion in one of the electrical plugs in the loom up towards the front of the bike, open them one at a time, check for corrosion, scrape away if any and then a squirt of wd40 will do the trick. Try the starter after each plug.

I reckon your battery's had it as it sounds similar to the way mine went down a few months back.

As my bike's got an alarm on it I'd had it on an optimate III & the green light was showing (indicating battery is fully charged & OK).
Press the button & wur, click, click. Bugger
Put the optimate back on, straight back to green light again
Disconnect & try to start, wur click, click again
Got the multimeter out & gave a healthy-ish reading of around 12.5v, pressed the starter button & it just fell away to around 9 or 10v.
Bought a new battery, charged it overnight (just to make sure ), fitted next morning, fired 1st time

After doing a bit of research online I reckon by keeping the Optimate connected all the time was effectively overcharging the battery & so I now leave it off & give it a charge once a month for about a day/overnight.

This makes interesting reading:-

That's his symptoms entirely, was hooked to my Optimate most of the day & came to green, also tried a car charger & battery not taking much charge. Only puzzling this which Dayz hasn't mentioned, it won't start when he attached jump leads from his girlfriend's car??

Dayz, looks like you'll be buying a battery as well as a chain - shouldn't have finished your second job!!

if a cell has gone down on the battery the bike wont run, not like a car where you can actually remove the battery while its and the car will continue to run

Dayz, Cornwall Battery Centre in Threemilestone, really good service good price and they deliver! Always get bike and car batteries from them !
Sounds like similar problem I had with my battery a while ago, but the cause was the regulator/ rectifier ov er charging it when it was running, basically fried the battery!

good luck

well from the message that was passed on to me we now suspect the solenoid being faulty as when bypassed the engine wanted to start. im not 100% sure on this as graham tinkered with my bike when i was at work and passed a message on through the gf who isnt the most articulate person and just explains things with "put an extra thingy next to the furthest metal thingy next to the edge"

also, badger i dont know if graham would have told you, after all that waiting and sorting (cus of my accident) we only attempted to fit my new chain and sprocket the other day, despite the fact the box says 108 link, it is infact 106 and too short so i think your soft link is holding my old chain together so i owe you a beer

As he said:

Tried Jump leads from car - alarm won't disarm until ignition is on, will disarm but solenoid only clicks.
Tried car jump-lead straight onto 'starter motor' output of solenoid & starter spins, bike still won't fire (presume not enough power in battery to spark?
Bumps starts OK when pushed.

If it was just the battery why not starting from jump leads? Personally suspect battery and possibly plus solenoid - any ideas from anyone else.

ps-before anyone else suggests multi-meter, my father has one but has just moved house & spent most of last night looking for his 'packed' multi-meter.

bump!!haha

He's sorted it, blown fuse in the alarm.
