I just completed this vintage Honda CB450 big bore race engine build and thought you all may like to see it! It has Mikuni 32mm carburetors, megacycle road racing cams, for the valvetrain I converted the engine over to 5mm stemmed black diamond racing valves and also converted the torsion bar system over to dual valve springs with titanium keepers, 74mm big bore pistons, electronic ignition, barnett clutches, I reworked the transmission to have a close ratio 5th gear, etc. I built this engine from the bare cases for a Brother over on dotheton so the build thread is over there with a lot of photos, if you would like to look at them here is the link - http://www.dotheton.com/forum/index.php?topic=27633.0

Here are the before and after photos of this engine build!
