    After struggling with getting the carbs on for over an hour yesterday, I'm going to ask. What's the "right" or "efficient" way to remove and install the carbs?

    The service manual just kind of skims over the carbs...

    To remove i just pull at them, easy enough, but to install i use a hair dryer to heat the rubber boots, which tend to harden over time, and the heat expands the rubber and the carbs just slide on.

    smear the rubber boots with a very slight amount of grease or Vaseline, jab #1 (or #4) as far in as it will go then tighten the clamp on #1 so it doesn't pop out.
    Now push the other 3 home.

    lube boots and carb throats start at 4 (or 1 )and then roll them in left to right put throttle cable on first.
    lube the hole and the pole

    I remove and install them with a long pry bar 3-4 ft I wrap the area wear I'm prying with form on the driver and install grease on the boots and play close attention to where I'm placing the pry bar so that I don't crack anything as it always makes me a bit uneasy, heating up the boots is a good idea too.

    I have stated to use ratcheting straps to keep constant pressure on the carbs. With the other tips above, heating and some type of lube on the boots, they seem to go in well. Pushing the carb to air box boots all the way into the air box really helps and gives the room needed. Once you do it a few times you will get the feel for it.

    DO NOT lube the airbox-to-carb boots, though. You need the stiction to help hold them onto the carbs along with the clamps

    Since the airbox boots, carbs, and the header boots are designed to all overlap there is no real space for maneuvering.

    A lot of pushing, pulling, twisting got the carbs in the right spot. Well, vaguely speaking.

    I get the carbs on the header boots by using rachet straps. That's a cool trick. Thanks for suggesting that.

    I'm struggling to get the airbox boots on the carbs..... any suggestions here?

    With more pushing, pulling , twisting, , etc..... but with fingers, hooks, prods, etc....... take your time and don’t get frustrated. A couple hints:

    1. heat gun will be your best friend
    2. DONT grease the airbox to carb boots. You need the stiction to Help keep them in place.

    The more I play with it the more I scratch carbs and damage the boots.

    hairdryer, 100 percent. Warm up the boots on the airbox side then push the boots into the airbox , just enough so they don't fall into the airbox and then the carbs just slip right off

    I have a piece of 1/8" brass rod with a 90 degree bend on 1 end. The hook is about 3/8" long. It works well to reach in to the warmed air box boots and work them over the carbs. It is long enough to reach into #2 & 3.

    once the boots are pushed back, the carbs can be rocked up and down as you pull them out. they come out easily like this. dont forget to loosen all 4 screws!
