Starting Issues Sp3se

Ride a Sp3 SE and looking for some assistance. Bike has just started having starting issues. Battery okay, electrics okay but when starting will only churn once before cutting out. This will repeatedly happen. Any ideas?

 

Thanks for the tips. Battery is on an optimiser and when tested showed 12.7v. The only other test was to try all indicators, lights, horn etc, they all worked. All dash lights as well.

Will get drop tested. Thanks.

 

Tested as suggested with car battery and roared to life. So, bought new battery. Is back up and running.

Thanks for the advice.

Back again. New battery worked for awhile now ignition comes on but when starter pressed nothing happens - no click,no turnover, absolutely nothing. Afters few presses on starter it will randomly kick into life. No issues when running. Any thoughts

 

Thanks guys. I have checked starter switch and kill switch both appear to function properly. Will check other elements and report back. Thanks.

 

Had a root around and did two things and she hasn't played up yet. First used my spare key on the of chance that the immobilizer wasn't been deactivated by the other key. Also found a connector leading to the earthing point that was squashed between the coolant bottle and the frame. Repositioned so now free. Don't know if either of these actually make a difference but is now working okay.
