lookin for a right side cover for my 1990 TW any idea what other years will fit.
I can explain it to you, but I can't understand it for you.
Powdercoated '87 frame, extended swingarm, YZ fork legs, ATV tire, 14/55, XT350 tank, spliced quick-release seat, disc brake conversion, beeg headlight, beeger rack, Lizrdcooler, Lizrdventz and bunch of other stuff all covered in invisible ink.
The correct Yamaha part number is 3AW-21721-10-98 but it is now obsolete. Like Lizrdbreth said, they all interchange though, it's just a matter of different model years being different colors.
I sent you a message. I've got one I could sell ya.
