My local Harley said at their schooling by the MoCo,  they were told that the current M8 was built to handle up to 130ci without case mods. But as of yet they have not come up with anything larger than a 117 ci displacement. I can only assume it has to do with EPA compliance issues. But they said they were also told, "bigger is coming". They are thinking that the 114ci will be the new normal powerplant with a 121 or 124 offered in the CVO.

I can tell you this; The head's were designed with something big in mind.

If that's the case, I have a recipe for a cylinder head that will blow the lid off on a big motor.

The Leading Edge link is dead now. They must have given up on the 151 kit.
