i just changed the oil in my wifes 350 that damn thing took almost 3 quarts... i cleaned it up real good. i took the S/A off of the pipe to see how it sounded and give it a test ride down the street. Just with the s/a off it seemed to wake the bike up a little i sat back on the seat and lifted the wheels in first:rockon: i did put it back on since i don't have any jets and airfilter can you ride with no s/a or will that be too much on the stock jets
