    removing installing carbs | GS1000 '78

    Hi Community,

    [GS1000, '78, no pods, original exhaust]

    I just (amongst tons of other things) put in new intake pipes (the once between engine and carbs). It was really hard work getting the carbs out as well as back in... had to heat up the airbox and fiddle endlessly to squeeze the carbs in.

    Is there a preferred method to get the carbs out?

    thanks for your insights!

    Are the airbox to carb hoses soft or have they hardened with age?

      ah... nothing to compare with. I'm in Europe, it was very cold so yeah - the hoses were pretty hard, but once heated up with a hair blower, they were very flexible!

      pulling the airbox of was easy enough. I'm just still curious as what the best sequence is to get the carbs out: do you pull the carbs into the airbox away from the engine, then pull the front of the carbs above the intake pipes? Or rather push the carbs towards the engine, freeing the side towards the airbox, trying to wiggle the carbs out from there?

        Undo the airbox, then remove the airbox to carb hose clips and pull the airbox back as far as it will go. Undo the carb to head hose clips and pull the carbs backwards. If all the hoses are soft the carbs will pull out pretty easily.

          As was stated, pull the airbox all the way back. I use a bungee cord to hold the box back and free up both hands. At this point heat the airbox boots AND the intake manifolds and work the carbs out. Cold stiffens the rubber so as supple as you can get it the better. A little wipe of oil in the intakes will id with the installation as well. Just enough lube to get some slippery going is good enough.

          I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

            It helps to rotate the back of the carbs up when you pull them out. Same when you put them in

            Take off both side covers and pull the bolt that holds the rear MC reservoir. Remove the air filter box and you have even more room to pull the air box back

            Use a screwdriver to pull the top of the rear boots off the carb mouths before you wiggle it out
