1500 wont allow a start unless it's in neutral with the side stand down. Side stand up it should start regardless of gear of neutral is the clutch lever is pulled in. If the clutch isn't pulled in, it will only start in neutral. This is if everything is in working order and someone hasnt modified anything.
You can do some quick troubleshooting. Put it in N, KS up, see if it'll start, if it does, put the KS down, try again, all without touching the clutch lever. This should all start. Then do the same two tests again with it in gear with the clutch pulled in. Post your findings. Hope this helps...
