traded my 660 cuz of that oil burning problem,i can tell you that my 700 hasnt used a drop of oil in 2200 miles and the oil is still golden when comes time to change it,it is one awesome bike and im sure the 550 will be a hot sellerclutch said:I have had my new 700 for about three weeks now and I finally got a chance to ride it today.It was just a short ride but it is sure different from my 660. It steers better even without power steering and is a LOT quieter. It dosen't seem to have the quick power of the old quad and seems to have a softer hit. Oh well I just hope it dosen't suck up as much oil as the old one did. :ORC
