Good luck with the travel limited lifters. You do know that you can remove the HLT2 limiter kit??
I am going to try them. S&S says after adjusting to zero lash shorten them one turn as they will then have the advantage of a hydraulic lifter. It seems as if they will have about .041 off the bottom. I put the kit in so I can always take them out if not satisfactory. Will update after install but might be a few weeks.
Thanks!!

Yea I tried them once. Knocked the **** out my lifters @1 turn from zero lash. (top down not bottom up) I collapsed a lifter twice at higher rpm. I disassembled all the lifters and took them out..

+1 on that. It's a great way to visualize what the cams and lifters are doing, then you get a good sense of what it looks (and feels) like above the cam chest for future adjustments.

I agree also, but interesting...

There's always some nuances that you learn about a particular discipline (in this case, HD engines), but when you learn theory (in this case, 4-cycle engines...ie intake, compression, power, exhaust occurring within 2 crankshaft revolutions (1 camshaft rev), you can apply it to any engine

We have clients report back to us using this method, that their engine is much quieter than stock.
Proper engine oil viscosity for the ambient air temps per the service manual also helps.

Scott. Was hoping you would add your thoughts on the travel limiters. Do you think they would be quiet if the additional one turn is done or should the above method be preferable and to not use them?

Thanks!
