Not a real involving question, but I'm curious...



Have some chrome carb covers to install on my 84 GL1200. Looks like just 4 screws to take the stock covers off. What should I expect when removing the old cover and installing the new? Maybe it's super simple, but I've never done it...



I've looked at a diagram, but didn't know if there's something special I should do or watch out for when removing or installing -- thanks

It's not hard,

But, there is a spring underneath that will go flying out......... across your garage if you aren't careful.

It's not a powerful spring so it's easy to hold in place. Just be aware that it's there.



Also the diaphragm that's underneath has a small loop. It fit's over a vacuum port. Make sure that it is in the right place when you put it back together.



The cover has a small recess on the edge near one of the screws. Make sure it lines up over the loop and the vacuum port. These three things have to line up or the slider won't slide.



Lastly, but not least, if the slide is old, the rubber diaphragm is probably well broken in and it will just lay in place. But when you put the spring back in and push the cover on, it will push the diaphragm out of position. You might have to take off the intake pipes, and stick your finger in and hold the slider in mid position to keep the diaphragm in place when you put the cover on.

The 1500 carbs are different, but the slider set up is mostly the same...checkoutthe first two pictures on this page:

having not done it as yet myself, but underneath it is a spring, needle valve, and a diaphragm, I would think you would need to take special care, when lifting the original cap as to not put a tear in the diaphragm

cheers,

Just go easy when lifting the cap, notice there's a tab on the seal and a notch on the inside of the cap that has to line up when fitting them back on, you may want to replace the screw studs also they are 4mm dia by 16mm long as shiny caps and rusty screws look a bit naff. Mine polished up brilliantly with Mothers Mag and Alloy polish (WallyMart $3.46) no effort in seconds

Looks like everyone has covered everything, except...

You might want to inspect the diaphragms once you get things opened up. Hold them up to a bright light and look for cracks or pinholes. Don't mix them up.

No holes or damage to the rubber that Icould see...
