It seems that cars and motorcycles these days are increasingly skipping on the torque in order to make big power numbers at high rpm. Since an aircooled XR is somewhat limited by design and dont like to be revved to death, I thought it would be cool to build it to not only make more power, but moreso impressive torque. My automotive engine building experience has taught me that you can run big valves and ports with a somewhat small intake and get about equal gains in power and torque.....relying heavily on the right cam grind. Since a diesel bike isnt in the near future and my diesel Dodge isnt either, here are my thoughts; A few mods that come to mind are bigger valves and just a light port cleanup, 10:1 compression(640cc if necessary), and a midrange oriented cam. I already have most of the other parts. Any thoughts or suggestions?
