Maxtorque has replaceable sprockets, but I'm not sure if you can
install a #40 sprocket to a #35 made clutch,
it's essentially a three row #35 sprocket with one side's teeth being filed down to slip through the bell.
(at least on my 12T Maxtorque)
So a 10T #40 would not drop through the 12splined #35 hole.
BUT you can swap the bell (with the sprocket)
for your maxtorque just as easily (in fact one snapring less to open)
And if you want to replace the entire clutch..
Surely maxtorque has a clutch for you.
you can spend hundreds of dollars for a race clutch if you want,
but I don't see why that'd be necessary
