I put K&Ns in both of my bikes. The 650 ran fine with it, I can't really compare it to stock though as the DSPO didn't have any filter in it at all. The 700 I noticed a significant difference between stock, and K&N. The K&N had a noticeable improvement over the stock filter at 6K+ on the tach. Below 6K it was terrible, between 4-5K it would stumble and backfire miserably. Once you got it past 6K though you better be holding on tight. I had to rejet the carbs to make it work below 6K. I do know that the DSPO for this bike had replaced the carbs at one point. I'm not sure if it had the stock jet sizes in it or not. I've heard the UNIs don't have this problem, but have no experience with them.
