Just took the Hyway big bore off the 660 and put on a Cross MMWS cylinder with a Hyway popup piston. The BB sucked gas like crazy. The MMWS seems to have snappier throttle response and a smoother idle than the BB kit. After a couple tanks will lean it out to 13500 and see what it does.
Here is a pick of the P&C I took off. About 14 tanks of gas with red armor at 40:1
