I owned a 1997 31 Open for 10 years and had to adjust the door trucks/rollers located at the bottom of the door several times to make it roll easier... I agree cleaning the track helps but over time I found the lower roller trucks moved somewhat making the door hard to slide/roll... Not sure if you are aware but at the bottom of the door there are 2 plastic plugs, 1/4", that will expose Alan screws used to adjust the lower door trucks. I made this adjustment and the door moved easily... M2C...
