this thread hurts me.. i just sold a cbr 1000 rr and my baby, a built 400ex that had substantial motor work. Im talking cam, flowbench, titanium valves, oversized piston, carillo rod, it was a beast. Ive had numerous bikes though I used to mx and flat track when i was younger. Ive had banshees, 250r's, but my all time favorite was a cr500 dirtbike. It pulled so hard on open throttle all you could do is point it in a good direction and hang on.
