bought a couple 800 Dragons to part or fix, the 2009 with blown crank (mag rod) is getting parted out as chassis is not so nice and the 2010 is getting fixed (bad crank and hole in case) as it is in very clean nice condition. Is the 09 engine compatible to use in the 10 as far as fuel system and wiring? Haven't pulled the 10 apart yet and not sure if it has CFI-2 or 4. I know the cylinders and upper cases are the main differences but will the 09 cylinders and case work in place of the 10? Cylinders and cases are in decent shape in the 09 where the 10 case is definitely worse (windowed). Had a buddy give me a 2011 case but it is CFI-2 and he has a decent cylinder to go with and if the 10 is CFI-2 I would go that route for the thicker skirts. Looking to see if I can build a decent engine and just do a swap one night. Limited shop space.
