XR400

Is that the engine with the really short skirts? I have seen some of those short-skirt engines come in with the pistons flipped sideways in the bore; not pretty. Yeah I used to be a Honda tech.
Back in the early 70s, a friend of a buddy had an XR 350. It happened one day that we found ourselves at the same redlite late at night; me in my almost new 1970Swinger 340 4-speed with 3.55s. My car was 14.4 second car on those E70-14 polyglass factory tires. When we blasted of, I watched his front wheel come up, and he hole-shotted the crap out of me. But I chased him down in second gear. That really surprised me. A flipping 350.........
