I have read thru some of the older posts that state the IMS seat and tank combo works well and I am wondering if the Yamaha YZ426 seat / tank will mount up to my WR426. I have some credit at my local Yamaha shop and if I can use it there it would work out better. The parts monkey didn't think the YZ426 would fit on the WR.... Any opinions on this? Thanks, Rod PS. Great site. I've owned a WR for a couple of weeks now and love it!!
