A 40mm to a 50mm conversion will cost a pretty penny. You need to replace all the components that fit on the axle (Brake disk carrier, wheel hubs, sprocket carrier, bearings..)and not to mention the axle itself. I am not so sure about the benifits, but with a kt100 I doubt it would make a large enough difference to balance out the cost of the conversion.
