If the starter relay is known good, then maybe the starter button is stuck as Lee said.
To test, use a meter to look for 12v on the Y/G wire going to the relay (push through the insulation). This is the relay control voltage. It should be 0v with the starter button released, 12v when the starter button is pushed.
Have you been having trouble starting this bike? Slow cranking and long crank times. That can fry the relay.

No I took all that apart and tested opens and closes when buttons pushed
I tested the switch it works let's power thru when pushed and stops battery died once last season this started outta nowhere always fired up pretty easy

This sounds like bad battery to me. Maybe.

Try this. Unplug the 4-position plug from the starter relay. This will guarantee the starter relay is not energized. If the starter motor still cranks when the battery is connected, then 100% the starter relay (even if it has been replaced) is shorted.
OK I'll try that but when I first replaced it was fine until I took it outside to fire it up then got stuck again
Any ideas why it would mess up a new one wanna get to the source

Take the Starter motor off and strip it and have a look.
This is from my old forum but the basics are the same,

Weak battery
That can be due to weak battery, poor contacts, or high starter current draw.
Excessive current through the relay contacts welds the contacts closed.

The only thing I can think of is that there's a short somewhere in the harness causing current to flow to the Relay as soon as the ignition is turned on. Can you get the bike into a really quiet spot and then turn the ignition on and try and hear if these is any arcing/crackling. Can also be done in the dark to watch for arcing.

You could also unplug the starter from negative and positive. Then try using a meter to trace back until you find the short, or bad ground.

Try this. Remove the starter relay from the bike. With the relay on the bench, connected to nothing, measure the resistance between the heavy lugs (large lugs in the image below). Test all three relays. What do you measure?

If all three relays test bad, I think I’m going to lose it…
