With an 09 flash on the 08 m1ks a reverse helix and a few harness mods you can run the motor in reverse on you sled if you put a dd lite or an 09 dd. I don't know the spesifics but it only works on the 08's not the 07's and the oiler doesn't work in reverse like the 09's so you can leave it in reverse or idling in reverse too long.
