Taking off the carbs

This morning I took the carbs off my Pacific Coast.  The hardest parts of the operation were 1) figuring out how to get the throttle cables detached and 2) freeing the carbs from the engine.  Here are a few photos of the process.

Air filter off. Rags are stuffed in the carbs so rain/dirt/etc doesn’t fall inside.

The bike is positively looking like a parts bike!  Here the carbs are removed.  Rags are stuffed in the holes leading to the pistons and in the larger hoses that I had to disconnect.  Make sure to do this job in a well ventilated area.  Lots and lots of gas came out when I pulled off the carbs.

  1. How difficult was it to disconnect the carbs?
    I am trying to take mine off.
    I loosened the screw at the base and pulled. Nothing happened. Is there any other thing I should do?

    1. Hi Marc,

      The first time will be difficult (learning curve and it’ll be a bit stuck) but after that you shouldn’t have any problem.

      Do you already have the air cleaner off? Have you disconnected the throttle cables and choke cables? The fuel line? The screws (one for each carb) identified as #7 on this link are the ones you loosened? https://www.douglasvanbossuyt.com/honda-pacific-coast-pc800-service-manual/pc800-service-manual-chapter-5-fuel-system/page-5-4/

      When I took mine off the first time, I ended up thoroughly destroying the carb insulators (those two round rubber bits that connect the carbs to the piston heads). Mine appeared to be original to the bike (an ’89) and were old and very brittle. I replaced them with new insulators and also put some tuneup grease on the insulators to make it easier to remove the next time.

      I hate to say it, but you might need to pull harder if you’re satisfied that everything has been disconnected and the screws on the carb insulator band clamps have been sufficiently loosened. I ended up using a big screw driver to pry them apart. It was a bit of a violent procedure.

      Good luck!
