Right. There are, without a doubt, overbore kits available for the 220. Regardless of what the manual says, it can and has been done many times. This can't be done on the E series models due to lack of clearance for the power valves. You simply can not go any larger on the bore without interfering with the valves operation.
I'm not sure on the KIPS activation. The governor in the case seems to be exactly the same. the only difference I can see looking at schematics is the top portion of the rod, and of course the entire mechanism up top. It seems like the parts in the bottom are the same. It actually looks like the actuating rod from the 220 would bolt into the older 200 just fine.
