...tip: find a larger diameter (and taller too, if possible) intake air-cleaner & air filter assembly.
...with more surface area per volume, there'll be less impedance to airflow, and thus easier "breathing" of the engine, both for FE as well as HP at wot.
...also, those large diameter "straight-through" mufflers are the beginnings of today's "fart-can" mufflers seen on too many rice-rocket vehicles.
