My front tire went flat over the winter and somehow now the front left fork is messed up.... I changed the oil in it and it didn't do much.... Still no compression or whatever? .... It's not leaking and I have know idea what to do now? A local shop quoted me around $400 and I have to take just the fork in. I think that sounds crazy. A fork on ebay was $110 ... Is that my best bet? I know nothing about mech of the trike so doing it myself is not a good idea. Thanks for any help!
