Went riding with a friend last weekend. Traded off between a yz400 and a tt-r 250. Loved the power of the 400, but the button start of the 250. So neither bike is a WR, I know. I'd like to get a WR400, (for reasons of $) but the electric start on the 450 is so nice. Anyone figured out the price and feasability of retrofitting the electric start of the wr450 on the wr400 or 426? Haven't found anything and was wondering if anyone else had looked into it.
