Don't have a WR, but am considering looking for one in the off-season and have a few questions. What years had what engine size. I see that there are 400, 426's and 450's. Which years had the electric start? Are these bikes able to be dual registered in CA? I know you cannot do it any longer, but would look for one that is already done. Are any year red sticker bikes? Pros, Cons???? Thanks guys!
