S&S lifter choice?

<< < (3/7) > >>

HD Street Performance:
As further evidence consider the 03-06 cvo 103. Same springs, pushrods, and lifters comparable. They did not eat lifters. Lofting a roller lifter murders any of them.

Please elaborate more. As I have a 2003 103".

HD Street Performance:
Well those cvo 103 heads have the same springs and similar valves to the 110 cvo head. They didnt burn through lifters.

timo482:
am i reading that 255 cams may cause trouble at 3000 rpm? i thought it was at high rpm that they caused trouble???

HD Street Performance:
Yes, the cams have very fast ramps. When cam is changed these lifter issues diminish with many grinds.
