M900 Starter Q

Bike M900 1997

Just quick Q, sometimes when I try to turn the bike over in the morning after it is sitting up all night , it sounds like the starter just spins up (high pitched spinning sound) as opposed to the crank trying to turn over the pistons on compression

It is completely random if it will do it on hitting the starter button but only consistency is , it happens when the bike is stone cold

She starts up great once warmed up

Maybe it is from a weak battery? Even though I drive it daily , battery needs a charge after 3 weeks (no means of using a trickle charger unfortunately), 2 phase system is not great

I am in the process of upgrading the cables with Exact start cables , nearly twice the guage as the OE

Battery is a few months old, I think I will have to take it out every couple of weeks to charge over night until I have provision to use a trickle charger
