I am most likely going to buy a new bike relatively soon. I have been riding a WR426 (2001) free mods done but no electric start. I ride mostly trails and am thinking of going with one of the 250's. 1. Will I be happy with a 250? and 2. Would I be happier with the YZ for the extra punch and light weight since I have never had an electric start model and I have never had a problem starting the 426. Please let the opinions fly on these bikes or any others that might be a good switch.
