I just got my 2010 crf250r's top end rebuilt, and i brought it home and it started leaking antifreeze out of the bleeder hole i think its called? Does anyone know why or how to fix it?

Are you talking about the drain hole in the cylinder head or the weep hole on the right inner clutch cover near the water pump?

1.)If it is coming out of the drain hole in head, it is most likely oil that either made its way in the spark plug cavity during assembly, or the gasket on the valve cover that seals the head off from the spark plug cavity is leaking/damaged. If it is coolant, your head is damaged in some way.

2.)If it is coming out of the weep hole on your clutch cover for the water pump, you need to replace the water pump bearing and seals and possibly your water pump shaft/gear depending on its condition.

Hope this helps

It was coming out the weep hole.. We just had the water pump seals replaced, but we took it back to the shop and i guess it broke again! The honda shop is fixing it for me! Thanks for your help though!

Make sure they replace the bearing as well! Could be why it failed again so fast.
