Well, I left my bike in my garage last night on the on postion with the key in the ignition hence the battery drained. Searching through some old posts, some of you said to replace the battery if it completely drains as it is shot. Is this always the case as I am broke right now and cant really afford a new a battery. I can bump start it, ( i think thats what it called) but after riding for like 20 minutes, it still cant start on it own once turn off. The most I got out of the 20 minute ride was a half a crank start. Then it died again. Does it take a while to charge while cruising and is there a certain rpm range where it will charge? In other words, can i just let it idle in my garage for 30 or so minutes and hope it has some juice for the next start?
