Hey all, Considering rebuilding my 1999 WR400 this winter, but I am also wondering if it's worth upgrading to an aluminum frame machine. I also would like to put a Trick Dual Sport kit on it and will need enough power to run a DOT headlight that actually puts out enough light for night riding. Which year would be the best to get in terms of engine power / reliability / power output and why? Just looking for ideas. If i can't make up my mind then I will just rebuild my 400 over the winter. All opinions welcome! Thanks in advance.
