My 500 was +2 wide and -2 short and lowered (flat track bike) and only had cleaned up ports with an FMF. It was really quick steering and all compared to my 250. But it felt lazy power wise IMO. I wish I could ride a NICE 500 and compare to my 250 after I have the zilla arms squared away. I like my 250 better than the Zilla but I only rode the zilla once and not for a very long time.
