No - the only bigger top end would be a 250 and it would be easier to put a 250 motor in - to install a 250 motor all you have to do is redesign the frame. If you can find the parts to bore it to 66.5mm (std is 65) it will become a 208 and if you get the crankshaft stroke changed to 61mm instead of the std 60mm along with the bigger bore it will become a 212, but is it worth the cost? A stroker crankshaft is about $250 (if one is available) and a 1.5mm over piston is $100 - installing the stroker crank requires complete engine disassembly along with incidental bearings and seals (another $100), a bore job is $100 and if you are building a fire breathing 200, you may as well have the head rebuilt (about $250), try to get a stage 2 cam ($125) new rocker arms will be required with a new cam (and they are not available, but the OEM rocker arms can be sent out and hard faced (about $125) and then you will need a bigger carb and a performance exhaust.
