vibration reduction

learning as I go. I didn't forsee all this mess. I woulda stayed at the stock bore.

When I put an aluminum sleeve in there this year I'm gonna have it bored and plated out to 89mm also. I'm more interested in saving recip weight than trying to gain 1/2 hp in displacement. Also the aluminum sleeve won't have scallops either at 89mm.

With the Arrow Precision rod I want to use it should spin up a bit faster and vibrate even less than it does now

...and I'm wondering if a guy couldn't source out a Ti wrist pin? That should more than make up for a heavy Wiseco, or, make an even lighter Vertex or something?

i'd lighten it, why not cut material off the outside of the crank and fill it with an aluminum disk to go more, pvl, wossner piston, bore the crank pin, if light is required, it can be lightened.

Are you running a single ring right now?
