I’m after putting one of these motors in my old knuck frame. Now my 74” pan is a pussycat to start at 8 to 1 compression. What does anyone know about the new motors? Would like a 103” but what about starting it? I read that the F H P bike that went to Daytona was 120” or so with bags of compression and was easy to kick because of the cams. Your thoughts gentlemen. Also any dyno numbers and spec on the S and S Knucks anywhere? Thanks
