LSA Question

My intended goal is to have good throttle response and low to midrange torque. As some have said that I maybe satisfied with the way it already is and if so then I'll concentrate on the tuning of the ignition and carburetor. I'm looking forward to the learning curve
A cam upgrade from stock is still a good idea. The factory cam balances a bunch of considerations, having nothing to do with good power and torque production.

A mild cam, under say 215@50, will significantly pick up midrange torque and allow it to rev out nicely to 5000+. Without sacrificing much at all on off idle response.
