Cams & crank time!

I started making my Honda RC174 six cylinder replica last July and one thing that has been on my mind since day one is: ‘how am I going to make the crankshaft and camshafts?’

I remember this happening to me once before when I was making my Kawasaki V12 and I ended up completing the whole bike without a crankshaft because I couldn’t figure out how to fit all the parts into the available space until a while later a solution came to mind.

My Yamaha FZR250 donor engines have plain metal bearings and a forged steel crankshaft so this ruled out the possibility of modifying the original crankshaft
