A 2005 came in yesterday for tires and an oil change. The owner recently bought it. On its first test ride, I returned telling my Tech that the tranny shifts where extreemly bangy, and I kept waiting for it to hiccup in 5th ... but it never did. As it turned out, the oil was extreemly black, and only 2 qts drained out. With new oil and full, it shifts completly different and normal. This guys gonna leave thinking he has a new m/c.
