Hey up, falcon has a superb guide if you can manage to search it out. I referred to his guidance when I fitted the 4 x v front end recently. I gathered the bits together first (forks, yokes,taper rollers and a fazer stem), built the new yoke set and then changed the whole front end as a complete swap, leaving me a complete original front end spare. I think doing it this way breaks the job up into more manageable, realistic bits. The results are great as well!
