I have an Animal thats been modified and its always been a little sluggish at low rpms. After it struggles on a start is good and strong. Animal with a 308 cam, stock rockers, flathead crank and a 28mm Mikuni flat slide. Bought a longer exhaust pipe hoping to pick up a little more bottom end. Maybe helped a little. Will hit 9500 on the dyno but runs out of steam at 8600 on track. I do not know what springs it has. Its always been this way, showing a lot of promise but the low end kills it. Thinking its maybe timing. Before you ask a lot of questions I have little knowledge about other engine details. My first thought is that it could be timing. Where should it be and what else would cause this? Spark plug looks like it burns clean, perhaps on the lean side if anything.
