Question about 2001 Yamaha YZ 426 F
The noise is between a rattle and a spining noise.It does not rattle when it is idleing but it does when the choke is on or if you hold the throttle open a little bit. I thought maybe it was the timing chain tensioner but I replaced that and its not the problem. The valve clearance is good, and i put new rings in it.
Could be your Flywheel,The yz426 has a riveted flywheel,over time these rivets wear from the flywheel spinning around,causing a "rattling sound"or it may be your timing chain is loose or has been stretched.

Clutch baskets are a common problem in those bikes.
