Been having problems with my bike turning on to the poin where I have to get jumps, I put the battery on the charger and it recharges it and says its good but I'll go out riding and sometimes it will barely crank over and I have to get a jump and sometimes it will crank right up, anyway I can diagnose it? Tks in advance guys.

 

How old is the battery?

 

Auto parts stores will test your battery for free, on the spot... Take it in, test it, and eliminate the possibility of it being the battery, then go from there.

 

The battery is at least a year old it was already on the bike when a bought it last July owner said it was bought two months before, when I try and crank the bike it doesn't start the next time I crank it I give it a lil throttle and it typically turns on but what gots me thinking it's the battery or stator is the fact that sometimes I go to crank it and it only wants to turn over once second time around it doesn't have power, don't know if I wanna replace both issues seeing how winter is around the corner and riding will be a lot less likely but don't want it sitting wait for summer to ride again.

 

I don't trust auto stores I took an optima in one day and the next day I came to pick it up and they said it was bad to leave it with them and buy a new one, took it home and went to interstate batteries and went back the next day, perfectly fine battery..

 

Put your voltmeter on it and see how low it drops when you're engaging the starter. If it drops below 10v with that little of a load, it's toast.

 

Should I charge the battery before hand?

 

Make sure it's charged first is all. If you would rather change it out first, you can. That would rule out the battery for sure.

 

ill slap it on the charger now ill post details later

 

also what if it cranks just fine how do i figure out the stator is bad?
