I have a 2000 YZ 426 in so cal and I am torn between the two. It has a problem with 5th gear, it skips dogs every once in a while. It's fine in all the other gears, but it is a problem. I have an aftermarket triple clamp with pro tapers, fmf pipe, GB mod, 03' cam, new tires and black or blue plastics, new x-ring chain and sprockets. It runs strong, but what do you think? What's one worth whole and is the sum of the parts worth more? I have already bought another bike, so time doesn't really matter. What do you think?
