I have a chance to get this 426 for $1500. The guy is second owner and has only ridden it 4 times in the last year. I currently ride a KTM 520 DS bike and would like a newer MX bike to ride the track with my daughter on her YZ250f. Also if I do end up with it, I have access to a blown up 04 450f. I have read some post about putting the newer plastics on the 426? What about the 450 carb is this also something I should nab and would it be a good swap. Here is a photo of my daughter, if I don't get on the track soon I won't be able to keep up.
