Anybody running the new Zip Ty magnetic oil filter cover?? I just put one on my new '05 YZ450 and am excited about it. Also, has anyone ever had problems accessing the oil screen? I am having terrible difficulty pulling it from the frame, can't get it loose & don't want to break anyhting. I am hoping the mag oil filter cover & mag drain bolt help in the time being. Oil is very clean after break-in, which is good. Ideas, Grey?
