    butterfly bushings

    ok im back...... im in the middle of cleaning my carbs and im ready to dip carb num 3 ..... i was ready to put it in the can when i noticed that the butterfly rod had some bushings that apear to be eather neoprene or plastic on it ..... the problem is that the only way to remove them is to take out the two screws that hold the butterfly on the rod.... in my experence of rebuilding carbs ( ase certified mecanic) those screws eather strip or damage the butterfly rod they are on ......
    so my question is do you typicly remove the rod and the bushings hoping not to damage anything. or is noone experianceing any neg side effects from dipping the carbs with the bushings atached.

    bike is a 80 gs 1100L
    thanx mitch

    oh and i read the carb papers and didnt find anything ......

    Dip the carbs with the seals still installed but I recommend only dipping the minimum amount of time necessary to get them clean inside.

        Yep, Ness is right (again).

        In the last several years I think I have only heard of one guy that removed the butterflies, then asked about it.

        I can't tell you how many carbs I have dipped, but I tend to leave each one in for a full day and have not noticed any problems (yet).
        I actually forgot one carb in the dip for three days. That carb is still in use in my stable, have not seen any problems because of the dip time.

        Use as little time as necessary, but don't worry if it takes a full day.

          Dip them if the alternative is pulling the butterfly's.

              I rebuilt a set for a guy that stopped through here a few years ago. He was up against so I offered to do them for free and shipped them back out of pocket. I even paid for the o-ring kit and gave him manifold gaskets and a petcock I had lying around. Anyway, I removed the butterflies without any problem. The o-rings on the butterflies are probably the most important if you're worried about air leaks. It all went back together without a hitch.

                  Nothing special, just made sure to use a screwdriver that fit the screw heads correctly. If you're worried about them vibrating loose a little Loctite should do the trick
