03 YZ450, the leak is coming from the front of the engine where the radiator pipe hooks in the engine, right next to the exhaust. I have taken it apart twice and replaced the O ring but I cant get it to stop leaking. I also have the pipe insert that goes into the head but I cant get the old one out. Any suggestions how to fix or what I am doing wrong? It sure seems to be a sloppy fit the way it goes together there.

Ace hardware is my new o-ring outlet. They have hundreds and at 60-80 cents a peice, they are way cheaper than cycle related sites or dealers.
