@MartyP - This thread might be a start or guide for what you seek.

If you're looking for a direct replacement then it's a +1 for Betony's post above but there are alternatives.

FWIW I replaced mine with the Yausa OEM original - Pricey, but each to their own.

Be extremely careful when you put the new battery in @MartyP. The battery lays on its side and a few people have got the polarity of the terminals swapped, with fuse blowing results.

Yes.....it can cause a lot of headache but no permanent damage.  Been there and done that.  😬


There is nothing like spending a day riding with friends in the grip of a shared obsession.

Can you just drop the Yausa in or do you have to flip it around to match the terminals?

Yes, you will want to install it in the correct orientation, pos to pos and neg to neg.

What's the ideal RPM's and gear for optimal charging of the battery. I do a short commute to work 6 miles 30 minutes and I am having issues with my battery holding charge. My scorpio reads 12.5 most of the time and occasionally it will got to 14.1 if I do a longer ride. Thanks

@MartyP I would keep the battery on a tender when not riding to keep it at full charge. Heated gear and other electric accessories can drain the battery in stop and go low rpm riding. The stator puts out more power as rpm increase.

I live in an apartment and have no outlets to plug the bike in. I have to use a battery pack and only lasts a day.

Most manufacturers specify charging tests at 5000 rpm. That’s not far in the FJ’s rpm range but there you go. 
 

you need to run an extension cord and charge it properly overnight somehow. The bike WILL NOT charge a weak battery, it will only keep a regularly used and charged battery topped off.

If the battery charge only lasts a day, it sounds like its time for a new battery. 

If you have a multi-meter, check the battery.

How do you know if your problem is really your battery? How do you know...

I meant the battery pack that I plug my tender into it only lasts a day. Looking at a battery generator but they are $$. I do have a volt meter and my alarm has one as well. currently it show 12.5

Low. The FJ starts best around when it has 12.7-12.9v to play with.

here’s another test: turn on your key and let the bike sit powered-on for about 30 seconds. Measure your battery voltage with key still on. Less than 12.1-12.2?  Dipping well below 12v? 11.8 or less? Your battery is toast.
