I put a new YUASA 14Ah battery in my LIKE200i 2.5 yrs ago.
I know EFI engines like a strong battery. and have been staring at the little 6Ah battery in my 3 yr old Piaggio. (I trickle charge both scooter's batteries if sitting for a couple of days)
Sadly, the battery compartment on this scooter is too small to accommodate (or be made to accommodate) anything more than a 6Ah battery.
So, thinking I might ask Santa for a new little YUASA for Xmas this year.
When I ride miles away from home on so many cold winter dawns - I like to know that I can just touch the start button when I'm getting a little chilly - and am ready to head home!
As I've noted before - these scoots require so little $ to keep them maintained each year - I don't mind spending a little on fresh batteries every few years.
I do a lot of roadside farting around! Stopping and shutting down, idling, re-starting, etc.
