first of all i want to say i have done a search on this and read those threads, but the op of those threads hasnt given a full decription for other to help solve their problem. instead of just saying it wont start and having other shoot out anything they might think could be the problem, i would like to narrow the problem down to 2 or so possibilities. the bike is a 1990 honda cbr250rr. i just picked it up the other day. when i went to have it a look at it the 2 days, it started fine. after i had it delivered it wouldnt start. when my friend and i first tried starting it up, it made the sound as if it was going to start. the sound was quite loud. we tried for about 5 minutes or so then we thought it was just low on fuel, so we went out and got ourselves 3/4 of a tank which is obviously more than enough. after filling the tank up we tried starting the bike up again but it wouldnt. played around with the reserve, unsure which way is which. after trying a couple of time the sound started to weaken, eventually the sound faded away. the only sound we could here were some clicking noise coming from the back, i believe it was coming from the battery area. after trying abit more that click noise became buzzing noise and soon that faded away aswell. then it made no noise. we tried all possible ways to start the bike. choke on, choke off, clutch in, clutch out, throttle, no throttle, roll start, 2 person roll start (me pushing the back). we mixed and match all those possibilities and still wont start. we tried looking for the kick start but i dont think this bike has one. we made sure the bike was on neautral, sometimes trying on 1st gear. and the stand is up. we came to the conclusion is it the battery because of the following symptoms 1) the headlights are so dim you can see the fuse without having to squint 2) the horn is so quiet you need to put your head up close to the dash to hear it 3) everytime when we press the start button the indicators on the dash dims 4) the neutral light is almost off 5) none of the blinkers work i gave the seller a call and he said i probably need to recharge the battery. i found my fathers battery charger which he uses for his car so im unsure if it will work, more importantly, will i blow it up infront of my face? it is a 12 volts 2.2 amps fully automatic charger. if it is usable, i dont even know how to recharge it, do i remove the seat and battery? so guys/girls, am i right about the battery being the problem here?
