Starter thud Noise

[chevysoldier]

This is my first post on here and I am really hoping someone can help me.Ok well since I have put the bike away for the winter, I am taking this opprotunity to fix some stuff. Besides cleaning the carbs and valve adjustment I am having a problem with my starter. I have a 96 FZR 600, non CA.

On mornings when its about 45 degrees or below, when I first go to start the bike up first thing in the morning sometimes when I push the start button, the starter will spin maybe once and all of a sudden it just goes thud. If I keep pushing it, I get the same thud over and over. If I leave it sit for 30 seconds or more, it usually won' thud again and will fire right up. I'm not really sure what this could be and am hoping maybe someone has run into this problem before.

could you describe the thud?

do the lights dim greatly when this happens?

Sounds like a new battery is in order.
