250-500cc Loose pink FMF silencer repack caused lean mid and top.

I recently repacked my long overdue stock silencer (WR250) with the loose type FMF 2 stroke packing. The bike is a lot quieter but also feels lean in the mid and flattens out on top like it's lean on the main by 1 step. The factory packing was the white roll of packing just like you can get from FMF but I wanted to try the loose pink FMF 2 stroke packing. It's no biggie to re-jet but I was wondering if anyone else has experienced this. Also I was thinking I may have packed the silencer with more packing since the loose packing fills every bit of the void unlike the roll type that slides in leaving a gap. Even feeling a bit lean there is no loss of power in the mid and after spending the past 2 weeks riding my 125 the front wheel on my 250 was off the ground most of the time.
