277 Rephase

I am looking at rephrasing my 78 650. A friend of mine can press the crank but we need some instruction on rephrasing the crank. Does anybody out there have the instructions. Or is this something best left to somebody like Hughs Handbuilt. Who else does crank rephrasing?

Thanks
Al

Hugh has written a detailed article on rephasing a crankshaft. Have a look around his website. If it's not on there he will have a link to it.
