    Intermittent staring issues

    Over the last few years I have had intermittent starting issues. For a while now it has only started when in neutral with the side stand up and the clutch in.
    Normally it would start fine after rolling a bit forward or backward. A few weeks ago it just wouldn’t do anything when I went to go to work. I tried it again and it turned over on the first touch of the button.
    The next day it wouldn’t start when I went to leave work. I actually ended up bump starting it to get home.
    I suspected the side stand switch as that can play havoc on things. So I bypassed it. Then I could get it to start with the stand down sometimes.... so I suspected the clutch micro-switch.
    I replaced both the side stand switch and the clutch micro switch tonight and it still won’t start unless the clutch is in the stand is up and in neutral. And even then it doesn’t always start.
    When it doesn’t start there is a click under the seat, and the neutral light dims just a little bit, but no joy.
    Now the only thing I can think of is the relay or the clutch position sensor (which I don’t really know what that would be).
    Any insights would be appreciated.
    Can I test the relay? Is there an aftermarket option that doesn’t take 2 weeks to get?

    for the capo usually there is always some handy solution off the shelf, did you tryied to see if there is any diag code coming up ? and of course that means knowing capo have diag installed from a factory it is under the drivers seat two small long white male female connectors that need to be pluged together , then you turn the key, turn the kill switch and insted of clock on the dash you get codes

    Replace the starter relay a be done with it. The other things you replaced were completely unnecessary.

    I was afraid of that, but everything I read indicated that the relay was the least likely culprit.
    I think the side stand switch was on the fritz anyway so I guess I probably have an extra clutch micro-switch, and pulled the dash apart for no reason.

    No codes. And I even checked with Tune ECU.

    The clicking you heard was from the starter relay being energized but not being able to make contact.
    As long as you have engaged neutral it doesn´t matter if the side stand switch or the clutch switch is defective.
    The starter relay can energize anyway.
    Dont buy a cheap starter relay.

    Not sure about this, you need to check - but hasn't the standard starter solenoid/relay been upgraded by Aprilia? If it has, see how much from AF1.

    I replaced the solenoid with the Yamaha part because I could pick it up today and everything works as it should now .

    Clutch-in starting is less work for the starter in any condition as it doesn't have to turn as much mass. I always start clutch-in out of habit for that reason.

    I didn't realize that, and since am in the habit now of clutch in to start I will probably keep doing it.
    Now I need to figure out why my battery died overnight last night
    Any pointers on finding what would drain the battery would be appreciated.

    The classic move for the one-time flat battery overnight is turning the key past OFF to the position that activates the little parking lamps. If it happens repeatedly and you're not doing that, something else is up.

    I was hopeful that it was that I had accidentally turned on the parking light (what exactly is the point of that anyway?) but the same thing happened yesterday morning.
    Guess I’ll be pulling everything apart again

    Has it got an alarm fitted - they are know to cause problems. Otherwise sounds like your battery is knackered and not holding charge
    I'd rather have a full bottle in front of me than a full frontal lobotomy
