yz 250 lower rod bearing replacement

[Texophilia]

Hi guys, I just picked up a 2000 yz250 for a decent price. The guy i bought it from just rebuilt the top end and said he had put about six hours on the bike when it started rattling real bad. He pulled the top end off again and noticed that it had some play in the rod bearings. The top one looks pretty straight forward to replace, but the bottom one looks like quite complicated. Is this something I should try and replace on my own or would I be better of taking it to a shop? Also any ballpark figures on what a bottom end rebuild would cost?
Thanks, Bob

You can split the cases and get the crank out without too much trouble. A service manual sure helps move things along. You'll want to send the crank to someone to have the new rod kit pressed in though. Not really something you can do at home.
