I just bought a 00' YZ426 thats in "good" condition. I bought it from my brother to help him out and didn't pay much for it. It runs great and starts first kick hot or cold. My other bikes are a 05' YZ250F and a 01' DRZ400E/street legal (barely). I have the 426 for sale for $2750 but have had no bites on it. So now I'm thinking I may just keep it since my son will be riding the 250F next year. I have the itch to have a lightweight big-bore with an auto clutch but don't know if i want to dump that much money in the bike. It will need some suspension work to make it race worthy and about $300 worth of other stuff for my preferences as well. Has anyone else gone down this road lately? Should I dump it and get a later model 450?
