If I hit the lottery I would make a totally new cylinder head. The valves are way to small on the stock 250 engine. And the air injection is a very bad thing.
To get tat kind of power from a 249cc engine will require special attention to the cooling of the exhaust valve. And a giant pile of cash if you want it to last

The takai coils and true kevlar clutch with heavy springs are the way to go.
Durability is key. At this point, I need to get mine back on the dyno but I am real certain it will show 40+HP at the rear wheel. With this setup, there have been some crazy issues that are being addressed now.
