Welcome Kymco Owners!
My mechanic, who has been working on Kymcos for years, said that he tightens the oil filters on Kymco 500 bikes tighter than the normal "hand-tight" standard. He said he's seen the filters on 500s work loose in the past. Just passing it on.
I use the torque wrench. The recommended 8.6 ft/lbs is considerably more than hand tight.Richard L.
Richard - which type/brand filter wrench do you use?
