Whilst on the parts hunt I found these.
Both rods are RSC race, rod on the left if for cb900f the rod on the right is for big gudgeon pin slipper pistons and short stoke RS1000 crank.
The crankshaft on top is standard cb900 in great condition if a little dirty. Crank on the bottom is a works lightweight short stroke crank, note the wider primary and skinny webs which cast not machined.
Wider primary chains, these are wider than 750 or 900. The longer chain is for Cb1100 the shorter chain is special length for short stroke rs1000 which has different number of teeth on the crank sprocket.
