Slow starter

Post by Justin1200 »



Hi, when the bike is cold, it’s starts normally, no issues. Once warm, the bike loses almost all power and the starter turns really slow, the clock resets (like it ran out of battery), and it doesn’t have enough juice to start. Once cooled down, it turns over like a brand new bike again... anyone else had this issue? New starter 2x summers ago. New battery at the same time.

Measure the voltage and current, cold and hot.

Where should I mesure that? At the battery? Solenoid? Just the voltmeter on the bike? Running or when off?

Current you can measure anywhere. Check voltage first at the battery (be sure to probe the actual terminal, not the bolt or wire end), then at the starter. Do this while cranking. Then you will know the voltage drop and the load. That will help you to zero in on what is causing your issue.
Too much current when hot, bad starter or something dragging.
Too much voltage drop, bad connections, solenoid, ground wire, etc.
Low voltage at battery, bad battery cell.
Compare hot to cold to see what changes.

Warm engines can cause higher compression which results in more load on the starter. Starter could be loosing some windings so it no longer has enough torque.

Most common starter problem is worn-out brushes. In fact, a relatively easy and totally inexpensive repair.
