I have seen it in here before, but cant seem to find the thread again. My question is this... I know a lot of us buy used bikes, what is a good checklist to go through while checking the bike out before the cash is dished out? I am going to take a look at a bike pretty soon, and I know you all have some great ideas as to how to check out certain things on the bike. BTW, I am looking for ideas for both 2 and 4 stroke mx'ers. Thanks in advance!
