In neutral it shouldn't be in the transmission. I would lean more towards a clutch issue or something similar.
I'll check that too. Have the front cover off anyway, but left the water pump bolted to the front cover.just a thought, what about the water pump impellor ?
video link is not working ?. and that gear dog is a tad rounded..lol. someone must be hard shifting at a high speed !..lol. prob reving it, and slamming it into gear, go figure for dummys..lol.https://www.youtube.com/watch?v=jrlWCsLw60Y&feature=youtu.be
Cam decompressor
This is a gear from the transmission
never gave it much thought on the decompressor ?. it just moves one way. as for the front cover noise ?. have a good look at the clutch basket springs on the big wheel. as well as the springs on the centrifugal clutch arms.https://www.youtube.com/watch?v=jrlWCsLw60Y
Cam bearings looked good, and the noise seems to be coming from under the front cover, not up in the top end.
How loose should the decompressor be?
Clutch basket springs looked ok. I had to take them off to get the clutch off when tearing it down.never gave it much thought on the decompressor ?. it just moves one way. as for the front cover noise ?. have a good look at the clutch basket springs on the big wheel. as well as the springs on the centrifugal clutch arms.https://www.youtube.com/watch?v=jrlWCsLw60Y

wow..lol, that shift fork is gone !. make sure to inspect the shift drum !.For comparison the center shift fork.
Might be a slightly bent shift fork?
Wondering if the noise I was hearing is the gear rubbing on the shift fork.
It's getting a new one either way. They're only about 10 bucks
That was my first thought too, but I checked, and the transmission was exactly the way it shows in the schematic, which makes me think the kid hammered on it and tweaked it enough to make it rubthat is definitely going to make some serious noise while running the atv. I'm sure that's the issue because it only makes the noise when driving and that gear is rubbing on the fork when moving.
I wonder if a thrust washer is missing between those gears?
Shift drum looks good. I checked it out after finding something very interesting.wow..lol, that shift fork is gone !. make sure to inspect the shift drum !.
