I build oddball sports cars (you can see what I'm up to at KineticVehicles.com). I have one now that gets 100 mpg, it's powered by a three cylinder turbocharged Kubota diesel and the R3 mill would fit right in there. So I bought a 2004 model that had been rear ended, I've ridden it around for a while, and...well, it's too much bike for me (and I'm a former open production road racer) but ooh baby, that motor!
