Melling JB-2079
Picked up a set of Melling JB-2079 lifters today from Autozone (cost me $10 ea) for my 2010 FLHX. Can someone confirm what depth I should I preload these lifters? Will .120-.140 work for these?

You can measure the lifter travel before installing if you like, or you can verify the distance (or amount of turns) from zero play to bottomed out if in doubt. Make sure the lifter fully bleeds down if you chose this method.

i knew the oil hole was a bit smaller on the melling lifter but i had planned on swapping out the cups from my stock lifters to the SBC lifters to make up the difference.

Not all lifters are the same. I know that the cups between my HD and S&S lifters are a totally different design. Let alone the difference in the bores...

Installed the Melling lifters yesterday after swapping the cups over from my stock lifters. Seated the push rods at .125. This motor has never been this quiet! Pretty impressed with these $10 lifters.
