About to sell 07 450r

After completely tearing down and putting my 07 450 back together I finally got to ride it the other day, it was great, went very well. Then I went to ride it yesterday and all of the sudden the electric start wouldn't work out of no where, all I got was a buzzing sound from the seleniod. Figured the battery may have died so I used the kick start instead and went riding for an hour. Got back home and it still wouldn't start using the e start. Road around a little more and then let it sit at idle and all of the sudden it shut off real hard, as if you would have stalled it taking off. Fired it back up with the kicker and road for another five mins and did the same thing again.

So I removed the batt. Cover and some of the connections on the seloniod were loose so I figured oh that must be it. Nope still nothing but the buzzing. I have 12v at the battery, seloniod, and contenuety in the positive to battery cable. When I hit the start button I have no volts to the starter itself though. All lights and everything else work fine. What am I missing I checked over everything making sure it was perfect before putting this thing back together, spent countless hours and money on it and every time I ride it I have an issue haha. Some one know what I should check next? Thanks

Anyone? I don't think it's the starter becuase of the odd random shut down while idling?

It probably was shutting down because the loose connections at the fuse by the battery box change the solenoid and be done with it

A good way to check if it's a fuse or solenoid is to use jumper cables and touch the positive side of the battery to the starter. If it spins the starter, problem is either fuse, solenoid, or bad ground. If starter doesn't spin, could be the starter. I had a similar issue and replaced the solenoid with a cheap eBay one that broke closed and tried cranking my quad when with the key off. The 2nd one I bought didn't work at all. So I bought an OEM one and worked fine after that.

how many volts are at your battery with the starter button pushed trying to start??
Buzzing solenoid is 99.9% of the time from a dead battery
