I have had my trike for 6 years and am still having a problem with the throttle assembly and cable. The sheath does not stay in the throttle assembly and the assembly is constantly sticking. It pulls the cable but one released there is too much slack so when I throttle again, there is not enough pull on the carb. I bought a new assembly and am dealing with this problem all over again. I used to use a pipe cleaner to hold the sheath to the assembly and that worked for a while. So frustrated. Do not have a push/pull assembly since VW is single cable. Going to try and lubricate the sheath today and see if that helps. If anyone understands and knows my pain, please reply.
