now that battery is off from the bike since 10 days and still be on 12.72-12.70 volts. I'm too stupid to understand if must be replaced or not....just becouse I don't know the real drop of voltage of a good battery after few days
I have issue with starting only when the voltage drop a little after few days of inactivity. I read somewhere FJR ECU drain a small amount of energy when the bike is off..
I bought the bike 5 years ago used with that battery installed on.And I don't know if it has been changed before.
Unfortunately on yuasa battery there is no manufacturing date printed
seems that after 4-5 days I do not run the bike, my yuasa voltage drop to 12.6/12.65 volts.I hear the starter crank it quite slowly...time for a new one? I don't want have surprises
when I pick up my bike on a ferry (going to Elba island) they ask me to put it on the center stand.But in my opinion is more stable on the side with the gear engaged..
..for example my FJR seat vibrate a lot more @5000 rpm when my rear shock is in hard position.I think any bike or mechanism vibrate, u cannot control it 100%
