does anything happen? does it crank, do you hear the relay click, or just nothing? The fact you can roll start it is a huge bonus in that it means its not a fuel or ignition problem and narrows the fault down considerably.

No clicks in the relay no noises at all

Check your battery voltage. If you don't have a meter try jumping it and see if it starts. If jumping it works, before changing your battery check the charging voltage. It should be over 14 volts, (If you have a volt meter) at some RPM higher than an idle, (3 or 4,000). If not that check the voltage at the starter when you are trying to crank it. If no voltage at the starter then check it on the starter side of your starting relay, etc. etc. etc. Good luck! Simple trouble shooting should soon solve the problem and I'm about as simple as humans get.

All good guys thanks. Had my mate who i bought the bike off come around with his multimeter and we isolated
down to the push button start, We pulled it apart and gave the contacts a clean and hey presto she fired up.
Thanks to Gadget the man with all the tools, I'm back on the road again.
