Sounds like that's your problem. Here's some info from Jeff K's Generic page to save a couple of bucks

Clutch lever bushing
The Honda part Number 2285-MBO-006 is $10
The Suzuki part number 59892-08A00 is $3 and exactly the same part.

Nope, that's not what that particular bushing does. See the photo below.
Up and down play is caused by wear in the pivot hole in the lever. On the OEM levers, that hole is in a bushing that is pressed into the lever, and cannot be bought as a separate part. Maybe it can be for Britman's aftermarket levers, but I'd be surprised.
