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...
I ride sleds and quads so I might as well join a site that covers both bases. I ride an 07 cat 500 and an 09 cat m8. I live in Anchorage Alaska.
Thanks,
James
