I have read a lot of threads and heard people saying that 4-strokes have a powerband like the 2 smokes, i"ve been riding 4-strokes my whole life and i don"t feel a powerband it feels about the same through the whole gear. I just got a 2 smoke CR80 this past christmas and i can definitly feel a powerband, it blows me back when i hit it, especially in 1st-3rd gear. Has anyone ever opened up a 4-stroke and a 2-stroke engine? Does anyone specialize in dirtbikes? Any advice is appreciated!
