It sounds like the front sprocket has something wrong with it almost like its not timed right. It's not startling, not grinding or screeching, just annoying humming when I enter 1st gear and when I get the wheel moving and the noise gets louder in 2nd, 3rd, 4th, can't really hear it in 5th cause the engine is louder than it. Im thinking that the rear sprocket isn't in cahoots with the front sprocket, almost like the front sprocket should match up perfectly on the chain but it doesn't because of the rear sprocket... so the top part of the chain may be tighter than the bottom part of the chain. because the rear is placing the chain maybe a millimeter too far for the front sprocket. I've been trying to send a video but It keeps turning out to be too long so I will try to make a shorter video and see if that works. thanks for the help guys.
Get the rear wheel off the ground with a rear stand. Sit down so you can sight down the chain. Spin the rear wheel, see if the chain is centered on the rear sprocket. Adjust until it is.

If your chain is adjusted TOO SNUGLY, when you set on the bike there will be No Slack on either the Top or the Bottom.
Re-adjust your rear axle/rear sprocket a couple of millimeters forward & try again.

But...make sure it is properly aligned. Using the marks on the swing arm are just suggestions..
