"2vm", I believe is 88-89 era. I did some searching previously to find out the year of some parts I have.

I have a brand new full clutch if you're interested.

I think from memory up to 94 cylinder will fit, 95-97 cylinders have different exhaust mounting.

I have the same in the shed, 2vm bottom end with 4ew cylinder but my bottom end is a WR

There's a 6' long spreadsheet on a site someone has done for x-reference Yamaha parts. Google it.

These are for 125 & I'm not sure on 250 and may be useless to you but figured id pass it on. Comparing parts #'s @ zilla should answer that?
