I have a 2000 426 with 450 ex cam mod. My question is should I spend $600 or more on a top end refresh and having the suspention rebuilt? I want to get a second bike and eventually something for my wife. The second bike would be a yz125 or something similar for me to play on and my dad to ride when he visits. I am just having a very hard time figuring out weather I should sink the money in the 426. Would it be more lucritive to trade the 426 for a 125 and just buy a new 250 or keep the 426?
