  • Possible broken carb post repair

    Got a line on a possible post pin repair product for the carbs. It may or may not work on the Yamaha carbs but certainly starts me thinking. The site is a Honda site but their bikes share some commonalities with ours, within minutes I found some great carb rebuild tips.

    I broke the top off one of my posts last year (or the year before, I forget...), right along the hole for the float pin. I glued it back together with JB weld and it held for about a year or so before it started to get loose.

    Having access to a machine shop, I took the carb in and made a new post out of aluminum and then machined the broken post flat and drilled a hole in it to fit the new post. I machined a reduced section of the new post to be a 2 thousands press fit into the socket on the carb and pressed it home. A bit of work with a file produced the flats and other geometry required by the float. I just had the carbs off today and the replacement post is still working perfectly.

      So....can I just send you my carb with the post that managed to snap in two spots to be fixed?

        That kit is very handy and creative. A member here fixed his with a section of bolt. I have mine wire tied.

          Only if you don't mind it going onto the end of my standard queue. That means it should be done some time before the second coming...!

            Hey, that should be just around the same time I get this thing running like an actual motorcycle again!
