Ive noticed that myself, my jardines have no soot inside so far, must be running pretty lean, Ive been a harley rider myself for years, i still have a 94 flstn, the 1340 is a reliable engine but lacks grunt, ive fitted a 127 cube el bruto, shes realy got some serious power now, Gotta love the rocket tho, Plenty of grunt straight from the factory, great value for money and looks mean.
