I have this exact same issue. Bought mine this summer in the desert in California drove it out to nyc. It stopped working after the big snow storms in February. Any updates?
Two weeks ago I had the front AHC shocks replaced ($$$) because they were both leaking. Could have done full OME for the same price, but there are no good Cruiser shops in NYC so here we are.
I suspected that the mechanics hadn't bother to crank the torsion bars or bring the front pressure...
