400Ex rims are the same part#. I changed my oil after the first 1/2 hour, replaced both with Honda GN4,as per dealer instructions. There was some assembly junk on the filter after the first change. I changed it again after about 3 hrs of rding,this time Honda tranny oil went in the trans. and I'm using the HP4 gold bottle with red cap in the engine.
