I am currently buttoning up the finishing touches on the rebuild/restoration of my 99 wr400 streetmotard. But I want to make it look better/ more streamlined, my camel hump of a tank and seat are the ugly originals and after 7 years on the trail (sh*t that's old ) it's pretty obvious that there battered and bruised. So here's the question, will a stock yz 426 tank fit on my bike, I know it's got a small capacity, and I'll have to change the seat (thank god , time for something taller/softer ). But do the dimensions, bolts, and shrouds line up. I'm not planning on any distance riding (wrong bike to do it on), I just want to tear up my city streets in here in SLO (San Luis Obispo), and look good while doing it . Oh yeah, does any one know how many miles can be pulled from the yz 426 tank , I know this question may be better suited on the YZ forum .
