Swap 250-650
So I keep reading it’s not worth it or doesn’t fit to swap an 07 250 to any other motor. How come an 07 650r motor won’t fit. It’s only a 2cyl

Who says it won't fit? That's what they said about 300 & 500 swaps as well and plenty of people have done those.
All you need is: - donor motor - floor-jack to lift engine up into position - ruler - measure connection points for engine-mount - cut & weld as necessary for engine-mounts - install engine - install 650R harness and all electronics - voila! Done!!! BTW, 650R engine weighs something like 145-lbs. You'd end up with bike with wet-weight in 450-lbs range, or about same as 650R. |

the 650R engine is a relatively poor candidate because of the layout for the airbox and FI layout - the 500 at least shares the intake and exhaust layout with the 250/300
