You'd think Bell went thru all the effort to have a drop spindle cast, they'd at least get the spring rate right.
If same spring used for another application it should still b close, since minis pretty much similar weight
Doesn't sound like a shorter(& firmer) Bell shock could tighten up that ride either?
A motor swap would make it worse in most cases
I'd think most low minis would want both lowered spindles and springs
