Is my battery dead???
 

My bike sat for about 3 days with out a tender hooked up (keep in mind it started up fine 3 days ago too). I went to pull it out from garage and start it and it ticked and wouldnt start. Head lights were dim and flickered.
I used my neighbors harley to jump it and it started up great and stayed on. I did not ride it though to see if i can charge it though. After it was on for about 10 min, i shut it off and tried restarting it, and nothing. So im thinking its the battery.

If so , what battery is recommended? Thanks

Unless you left your key on there is a good chance that your battery is dead. 3 days is way too short for it to die. I would throw a charger on it and see if it will hold a charge and let it sit for another 3 days or so. If it won't hold a charge and after 3 more days if it still won't start then yes you need a new one. I have a Yuasa in my F4i and it is awesome. It is also like $160. I have a Bike Master in my RR which is bad so I have to buy a new one for that. I will probably go with Yusasa because they last a while.

unfortunatley i do not have a charger. I will get one tomorrow and try and see. As far as new batteries, is it better to order online, or jst pop into pep boys?

Batteries Plus. :icon_google:

I wouldn't go to Pep Boys. Been there done that got a battery that wasn't quite good enough after hours of searchjing. So I went to a local bike shop and picked up an OEM replacement. 96 dollars and a battery charge later my bike is running like a champ.....except for the blue flame it spits from the pipe...:icon_bike: lol.

+1 on the Yuasa for the F4i. Had really good results with them. Last a long time and don't die very easily from my experience.

If your bike started up just fine three days ago, and is dead now. I'd highly recommend looking at your charging system.
