I have a 2012 wing with a new CSC trike kit on it. I have put around 5000 miles on the trike kit since we bought it and the right front fork seal is leaking. For you CSC owners just wondering if at this time I should upgrade springs to a set of progressives and also the best place to purchase the seal kit. I also understand that the left fork has an additional bushing in it because of the anti dive, I have heard that adding this additional bushing to the right fork will aid in making the seal on the right side last longer?
