Ok, i have a brand new odyssey battery. It was on a battery tender and says its fully charged. I go to start the bike and it turns over real slow like the battery is not fully charged. Well i have another battery from a atv that is fully charged and i have used it in this bike before. So i try it and same thing. I go to jump it off my car and same thing. It just wont spin fast enough and after a couple trys it wont spin at all. Now a couple of time over the summer when i would go to start it, it would do this. But the 2nd time i would hit the starter it would fire right up. Do you guys think it could be the starter?

 

Sure. What bike what year? You may also have some type of ground/short that is draining voltage when you hit the button. Check all of your connections & ground strap first. BTW, nice avatar..

 

well i guess my trickle charger must not work to great. put it on another charger and it fired right up.

 

I have found that the battery tender will not give a good initial charge on a new battery. I have no proof just a gut feeling. I bought a new battery and it always felt weak. I did the initial charge on a smart tender. I accidentally left the switch on one day and killed the battery. I had to use an older 2 amp charger to bring it back. It has been performing strongly ever since. The smart tender does seem to keep it at the same level.

 

I wouldn't consider it fixed yet..Since you said that it has happened before.
First I would clean all electrical connections, even the ones that you think aren't in need. especially grounds to frame.
Secondly I'd run a ground wire from the battery directly to the starter, had to do this on my 02 FXDXT.
Also may be a solenoid with dirty contacts. Try everything else first.
