TJ,
I was working by the filter tonight and the silver clamps on the filter were pretty loose. Just a reminder to keep an eye on them as when I installed my filter I made sure to tighten those clamps pretty damned tight.
Also, I didn't like how the filter was unsupported and would vibrate a lot, so I rigged up some tie wraps to act as a brace. It's ghetto to the max, but the entire carb and filter assembly is now nice and solid. You may want to try this with yours.
I also used the rubber runner pieces from the stock airbox and used them to lengthen the runners from the filter to the carbs. I like how solid the runners mount to the carbs and how the other end of the runner slides easily into the r0990 filter's openings. Everything clamps up quite nicely.
