So I have got my trike finally riding awesome.1992 flhtcu Ultra classic tour glide. With front air suspension. Put avon trike tire on front 42lbs Fork pressure at 9lbs rear airbags at 80 lbs and BFG radial TA on rear at 20 lbs. Now I need to know is there an easy way to tighten bearing adjustment nut which is under upper fork bracket on triple tree. I am getting popping noise going over bridge on over passes and on rises in road and tightening that nut would do it. had fork tubes replaced last year because one was bent. took it in for air and oil seal replacement. they told me fork tube was bent. when they showed me it was bent but not much. Did not have that problem before taking it in. Would dealer have need to remove triple tree for replacement of fork tubes? Thanks for they help friends you are all very awesome!!!!!
