CBR600F4i Battery Thoughts / Suggestions / Things to Check

No, only as far as the initial off position but thanks for the thought

I'd disconnect it and see if it still goes flat, then you'll know if it's the batt or the bike.

Does sound like a fooked batt, but something must be killing them.

I killed a new one once in about 6 months due to not looking after it, letting it deplete too far etc.

Taking it to a garage to get a use of their battery tester would settle it once and for all. If you ask nicely they may not even charge.

Thanks very much guys for all of your advice. I had the alarm removed and the battery replaced (even once the alarm was removed it was too far gone). So far so good hopefully all sorted now. No other gremlins were noted, just minor chain adjustment, an additional spacer added to the centre stand mount and an extra cable tie to route the scottoiler without any potential fouling.

Happy, safe riding everyone!
