carb rebuild - '81 Interstate

Post by stancotreau » Wed Mar 02, 2011 12:52 pm

Well, it is finally warming up a bit so I am going to continue my work on my '81 Interstate. I am getting ready to pull the carbs and rebuild them. It has been many years since I have worked on Carbs.....

any advice for pulling the GL1100 carbs?
how about rebuild kits? their pricing is all over the map, any good or bad vendors / kits out there?
things to watch out for?

any and all info is appreciated

Make sure you pull the caps off of 1 &3 so the rack will clear the frame coming out the left side. Randaks is consider the top of the line. I would read over his tech tips for sure. Stay away from kits like the ones from Saber Cycle. Their stuff is lousy and will give you nothing but grief. A lot of times thses old carbs need nothing more than a good cleaning. make sure that the jet assemblies are removed and cleaned very well, surgically clean. If not you'll be pulling the carbs off two or three times before their right.

Getting the throttle cables off is a can try to take the air box out and reach down into get to them..I have to loosen my crash bars on the left side to get the carbs off. It's a tight fit a lot of wiggling and jiggling to get the carbs out. I also loosen the gas tank and knock it back 1/2" hat helps to..remove the fuel line and gas filter and change it out. When I reinstall I reroute the throttle cables outside the install and removal is easier and less of a bend in the cables. Also bench test your cabs for leaks before you re-install. Could save you lots of work, see the pic..Caps off, gas source attached and look into the jet tops..gas??? not good. Lots of good step by step carb cleaning threads on line at NGS and Saunders site also Randakk's. Also if you screw some 1/4" clear tubing into the drain ports..hold the ends up above the bowl lip put gas into the carbs you can see if you floats are set correctly..levels should be just below the bowl lip..kind of a real life check..carbs smut be level on your bench.
