I have sold a motor on here. One sold as advertised and the other ended up pulling some parts as it was going to be more of a street application. My opinion on motos is that what is not affordable today will be tomorrow. Look at 582 to 632 motors. Only a few select had them due to the price and you were doing good to have a 540 or 555. Now, you can't give away a 540 or 555 because everyone has an affordable 582.
