i am trying to register my quads in wi to be able ride the trails. i found it on the arctic cat, just found the serial number on the polaris, and now i need to find it on the 06 vinson. i registered it with my bill of sale, but want to verify it because when i tried to input it on the wis. dnr website, the vin did not register as it should have because it came from wis.

 

i'm pretty sure it's on the frame vertical/angle piece in behind the left rear wheel (as you sit)

 

after some scraping, i found it. thanks vinny04
