What year do these fit???

[tjswigger]

I used to have several KX 250's. I have these parts left.
Can anyone identify the years. I do know these are from 1988-1991.








 
Any help would be appreciated!

Hello.
I believe that cylinder is a 1992 KX250.
I have parted two 1992's out over the years and both were stamped 1671.
Check the pics out here:

I don't know about the crank, looks even newer then the cylinder..

well the cylinder looks just like the one on my 89 250, my crank looks different though, maybe the crank is aftermarket or something...

Hey guys, what are the four numbers stamped on the side of your cylinders?
All of the cylinders of that era will look similar.
However, the porting and exhaust valve configuration is what will get you in a fix.

my 91 is stamped 1643

92 = 1671
91 = 1643
90 = 1601
89 = 1566
88 = 1542

The cylinder is stamped 16 71 I guess that it is a 1992!
I was hoping someone might recognize the crank,I would like to sell these but need to make sure of year of each part!
Thanks Guys for your help! I will soon be posting some pics of my left over items!
Here is the  1990 250 I restored from a basket case!

1566 = 1989
1601 = 1990
1643 = 1991
1671 = 1992
1686 = 1993
1722 = 1994
1751 = 1995
1793 = 1996
1835 = 1997
1851 = 1998
1851 = 1999
1911 = 2000
1938 = 2001
1959 = 2002
