That is the way it sounds. It's not the lifters. Seriously doubt it the rocker shaft moving either. Mine does it at 45K and those shafts are tight. I sure can't hear it at speed at that rpm however for the wind. I can hear it at idle or sitting still at 3000. It hurts nothing. If you put a two ear stethoscope on it, bet you hear no tapping, just a smooth whirr. Muzzle the exhaust with a heavy cotton rag and most will disappear. I think it is mostly piston slap and exhaust resonating. OF COURSE, THIS IS JUST MY OPINION BASED ON WHAT I HEAR IN MINE AND OTHER STOCK TC88s. SURE CAN'T HEAR YOURS. IF YOU HAVE EVER HEARD A LIFTER THAT HAS LEAKED DOWN OR HAS TRASH IN IT, YOU WILL THINK THE MOTOR IS COMING APART. Adjustable pushrods are not necessary for a stock cam.

Not sure why an old thread coming back to the surface is a big deal... If it helps someone.. let it be.

Rockout inserts.

I've done them on two Twin Cams this winter/spring, and it's pretty straightforward.

A search here will reveal plenty of data. Here's my first install thread...: https://www.hdforums.com/forum/engin...014-flhtk.html
