Tore the motor apart a month ago, got everything i need to put it back together, and looking at this part, cant figure out where it goes or even if it is part of the engine, may have placed on my bench randomly. Od 31mm, id 19mm, width 15mm.
Its not the sprocket bushing, got that.
So is this a yz250 engine part? Been through fiche multiple times

Don’t know the year of your engine but that looks like the collar that sits between the primary gear and the main bearing on the early 2000 models

It should be under the clutch Fiche... look at 2000 model and a 2001 model you should notice a difference 2000 utilizes a collar like the one in the photo; 01 utilizes a Thin splined thrust washer... easiest way You would be able to verify is look at the old crank if it has a long spline on the primary side it uses the longer collar a short spline uses the smaller one...
