Are there any major differences between the two blocks? Just wondering if EVERYTHING from an f4i can be put onto an f4 block. Please reply asap as i have no experience with this part of the bike.

 

Might be a little bit to late since it is almost a month later but....... Are you planning on trying to turn your f4 into an f4i? If that is the case, I wouldn't suggest it. I looked into it about 8 months ago or so and it is more financially sound to just get rid of the f4 and buy an f4i. A whole lot easier than getting the ECU, cables, throttle bodies, gauges (not to sure if the f4 gauges will work with the f4i stuff) etc....

 

No, i have an f4i. I had a chance at a stroker kit, and the block that was bored was from an f4. I came to find that the blocks are not swoppable for some reason. I called numerous people, and finally got an answer.
