So I tried one of these out in a stock bottom end, 15mm dakar SHA clone, no porting nothing.
Running it with some 20w-50 oil
did not change the springs or anything, and this seriously feels like I have a 2 speed bottom end. It revs out hard and pulls great on the bottom end, and then boom shifts smoothly into "second". I don't even think I can rev it out on a stock jug...
