People say all sorts of things. With enough time and money I'm sure you could.

The stock cases can accept a sleeve OD of up to 93mm. With the 71.2mm stroke of the 350's crank, you would need a 93.9mm bore to make 500CCs. I don't know how thick a sleeve needs to be, but you're looking at widening the cases (and moving some case bolts) or getting a stroked crank. I've never heard of a stroked crank for this bike, but that doesn't mean someone hasn't made one
