Last year my dad and I got a 02 yz250f and 00 yz426f. It was my first bike so I started on the 250f. Now I have grown in skill and size(I am 6'3 175). My dad is 5'10 160 and is having trouble just with the weight of the 426 in the trails. I think we are going to switch bikes since I am younger and bigger. We ride only trails and mostly double track, much of which is very tight. SO since I am getting the 426 what should I do to it? I was reading previous threads and am curious? how well does the disconnecting the light blue wire work? what can I do to lower the weight? (on a budget) since I am riding tight stuff how do I make the wr puke tank fit and how much is it? will it be that much harder to handle in the tight stuff for me?
