Honda 400ex VALVES TAPPINGGGG!!!!!!
Hey everyone. im new to the forums. i have a queston for all of you.
My good friend is selling me his 2001 honda 400ex. He just recently put a high compression piston in it and new timing chain. The valves seem to be adjusted right. but the valves tap. they never stop. Hot or cold. you start it and the valves tap. the higher you rev it. the harder and louder they tap. he told me that is normal because of the high compression piston. i highly doubt that is normal. there has to be a way to fix this. does anyone have any good ideas? Please let me know. I want the quad. but not with the valves like that.
thanks, Vinnie
