VT500 Ascot Starting Problems


I have done a lot of research regarding this and am familiar with the starter clutch and solenoid issues. My issue is a little different. My symptoms are as follows:
When cold the bike starts perfectly.
When hot (after riding 1hr+) it cranks to slow to start.
However, when hot, you can bump start it with no issues.

I have clean the solenoid and it appears to function fine. Can the solenoid get worn and not carry enough current when hot to turn the starter motor fast enough?
Is it getting vapor locked a little and it's too stressful for the starter motor?

Any ideas would be very helpful!

The last of the V4 Interceptors....would've been a shame to blow it up.

Battery is the first thing Id check. Is there a sticker on the battery indicating age/date of manufacture. Can you try jumping the bike from another vehicle when it is warm? If it turns over and fires up OK would indicate battery. If it still fails to turn over with a confirmed power source then you can move on testing rest of the system. With a voltmeter across the battery terminals what does the voltage show when you are trying to start it hot? What voltage are you seeing on the starter side of the solenoid when you are trying to start it hot?

In happy automobile land poor cranking only when hot is usually a starter motor on its way out. Before you condemn it complete the battery check and make sure the motor and battery grounds are good. If all of that passes muster it is likely your starter motor is going bad.
