Does anyone know if a tank from a YZ (2-smoke) is the same as the YZF, is the same as the WR tank and seat? I want to replace the tank on my WR to make it lighter, and understand I have to replace the seat at the same time. My question is: I found a seat & tank from a 01 YZ 2 stroke, and need to know if it will fit my 01 WR426. The guy also has an alum sub-frame if that would fit I could shave 5 lbs off of my tank. Thanks!
