Since day 1 of owning the Ace I have been frustrated about how hard it is to slide the seat forward and backward. I knew that some grease would help a lot but just never got around to it. Today I needed to take the seat out to get to the oil filter a little easier and I almost pulled a hernia. I grabbed the bottom of the seat and with some jerking I finally got it out. Before I put it back in, I got my grease gun and applied a lot of grease to the outside of the seat rails on the bottom of the seat. She slides easy now. Sitting in the Ace it is easy to adjust the seat. Sure wish that I had done this sooner.
