hey guys im new to the fourm, hopefully someone can give me a little insight on my problem here. i bought an 09 Honda 420 from a friend that had just put a fresh top end in it. about 2 hours after the rebuild it started smoking again so he shut it off and decided he wanted to get rid of it. anyway, he says he called a mechanic and they told him it sounded like the camshaft bearing and the oilpump. does this sound accurate to you? im pulling the motor out soon and wanted to get some opinions. thanks!
