I've never been able to get YLI threads, including invisible, to work happily on my 4800: they jam in the top of the machine. I now use Superior MonoPoly when I need a clear thread : have just done a successful stitch in the ditch with that on top and Superior Masterpiece in the bobbin. The thread broke occasionally, but it didn't keep jamming the way the YLI does. The tension was tricky at first (always is when you show the 4800 a quilt!) but when I changed to a no.11 topstitch needle with the tension at 1.5 and stitch length 2.4, I got very good results.
