I was wondering about this as well last night.
I have HS40's on mine, as well as some RS40's.
The difference is the addition of an R, for instance:
So an HS with rollers is an HSR
A TM with Rollers is a TMR
You would most likely be interested in TMR's. The HSR's start at 42mm, they're Hawg Carburettors
