Bought a 08 with a grenaded pile of shrapnel the previous owner called an engine. Instead of rebuilding I found an 06 engine with low hours for a reasonable price. I know fitment is not an issue but what about electronic hookups? I know the magneto is different so I have a suspicion I might need the 06 cdi as well. Need some hard facts and technical info on if this it a drop in replacement or if other items are needed?
