See how loose the lever sits. There may be room to put in a spacer if it's that bad.
There is maybe an 1/8th of inch gap. The lever is definitely not "snug." It has play in all directions...Would aftermarket levers cure this?
Thats a $200 gamble you would be taking in hopes that it does the trick... A spacer would fix it for sure and cost you less than $1. So, really depends on if you just want to stop the lever vibration, or if you want to stop it AND improve the looks of the bike...
