Are the valves a direct fit or is machine work necessary?

Major Machine work would need to take place to make this possible. There is another option though and there is a lot of false information so far. The bore and Stroke of this engine is the same as the 07-08 r1. it is possible to just use the entire top end off of the r1 to make your fz8 a fz1000. The crank connecting rods and bottom case are the exact same part numbers. I am planning on making this happen. The Italian guy who did this used a throttle body off of a 2008 zf1 abn im going to try it with the stock throttle body and injectors before I consider going that rout.

The bore is the same. The fz8 has bigger sleeves. But same bore. Any progress?? I have 08 cams and gears, valve springs from pete beale racing (yamaha racer since the 80s) and the crank gear, new head gasket just waiting on winter to come in full. Anybody doing this please keep us posted of your results thanks!
