Ha airhead fans , Ive got a ticking Q for you all. I have a 74 R90/6 that has valve train noise. It is ok cold but at high RPM 4K + or when it gets to normal temp the valves get noise.... Ive adj. them and tightend the cyl. nuts and set the rocker so there is little to no movement between the blocks...... Maby i am to picky and this is normal, Does this sound normal to you? IF not do you have any sugestions.
