I have a 01 fat boy, was leaking oil like crazy got that problem fixed it was the vent on the tranny loose and leaking.... any way got it all back together and the chain was to loose and making a noise so I took it all apart again and fixed that.... now it wont start...all it does is go click click.. I thought the battery was dead because I know its on its last leg so I tried to boost it...nothing... put it on the charger and nothing... all I get is click click.. so now what do I check or where do I start... I am about to list this thing for sale.... i am atmy witts end...all I have been doing is fixing this or that nice weather finally here in the morning and my bike is dead....
