a well clutched and jetted piped mm700 is still a force to be reconed with as far as power goes. chassis have come a long ways and weight has gone down, but the yammy is right there on power and leads the pack on reliability.
run only the yamaha belts......they are bulletproof
the stock yoko track is pretty heavy but works ok, if you have some $$ to spend, find a 151 or better....odds are it will be lighter and treat you better.
bar risers and a lefty will help you flick it around easier....lots easier.
unless you really like to trail ride, axe the sway bar.
I have a roller in one and the stocker in another.....the roller does backshift better......I don't think I would buy it before a track, but if you find one for a good price jump.
mpi transfer rods are pretty handy too.
good luck.
