"...but,I guess my point is that with modern technology,they are able to produce 4-strokes with almost twice the displacement,but at closer to the same weight as 2-strokes. This will hopefully allow us to put larger 4-stroke engines into our planes that arent that much heavier then our current 2-strokers and still have the performance..."



I think I understand the statement but,what technology do you think they could be using to make a production, say 250cc 4-stroke, come out anywhere near the weight of a current production 125cc 2-stroke?
