Title: 1986 GPZ1000R Falicon supercrank
Post by: Chrome Megaphone on October 05, 2020, 12:35:03 PM

If I'm building for HP should I consider?  Falicon no longer reworks crankshafts, what did they do, lightened and neutrally balance?  Currently have ZX10 rods ZZR1100 pistons, GPZ900 cams, going to port the head.

I have the same parts {I believe}.
I forget which pistons they are, but their .080" oversized as I recall.
The Rods are longer than stock and the pistons have a wrist pin location that matches that rod length.
The pairing pushes the new piston about .020" higher than the top of the OEM piston.
ie; More compression.

I balanced all of my parts, and never got back to doing the build.

The pistons/rods you have are lighter than stock, so they shouldn't add any strain to the crank.

Ride safe, Ted
