Another point on bikesaws, look at those saws Dennis has pictured. The massive job of the conversion has already been done, just a simple tweak now and then will keep them competitive as long as there are bikesaws. Kartsaws did away with regular saws, bikesaws did away with kartsaws, is doubtful there will ever be a power plant that will put a well designed bikesaw on the shelf. Two stroke engine development has reached it's peak and now are being phased out.
I was thinking more CC-wise. Three hundred+ cc bike saw competing against five hundred cc saws.
