I'm looking at adding an EVO to the stable and am wondering what the main weak points of the EVO engine/drive train are.
T-man
A FXR 1-2-3-4 perhaps?
Really aren't weak points with an EVO
There are dozens of good, proven cam grinds....take your pick.
Change out the original INA cam bearing for a Torrington, and while you're in there, a steel breather gear.
Don't be shy with the oil changes....
These are the only things that come to mind on the weakness of an EVO.
There were porosity issues with some of the cases.....
There are numerous mild hop-up combinations that don't affect reliability with an EVO...
