I used to have a Janome 1600, and I did the same. I use the needle that is appropriate for the thread. A finer thread such as a 60 wt Bottom Line will work with a smaller needle with a smaller eye. A thicker thread such as 40 wt King Tut works better with a larger needle and larger eye, such as a topstitch.
