I am in the process of rebuilding the carbs for my 79 CX500. I am cleaning the carbs following Larry's Guide. This has been an excellent resource for the project. I had to revert to page 40 for removing the main jet/emulsion tubes. This process destroys the tube while taking them out. After doing this for both carbs I then tried to find new or used emulsion tubes. I have not been able to locate any, I tried to email Larry but did not receive a response back. Does anyone from this forum know where I could get a pair of emulsion tubes so that I can ride my project motorcycle in the near future. Any help would be greatly appreciated, thank you.
