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.
