Removing carbs out of a I4 (CBR600)? How do you do it?

[piresito]

I know, I know, this is a GS500 forum, altough I'm getting desperate...
I'm trying to get the carbs out of a CBR600 F4 and those fuckers doesn't want to come out. I've loosen all the clamps, rechecked everything but those gas suckers won't come out, they move just a little bit. I've tried also using two long wrenches to pry them out, but no success.

Anyone has experience with those?

Regards,

Loosen the clamps @ the engine as well - I think it has the clamp style ones that go on the manifold not the flange style.
Then lubricate the crap out of em, spray them with wd40 all over.
Then wiggle and shake and work em, and spray more.

Remember this ... getting out is less than 1/10 the difficulty of getting it back in.

Lube and put a 2 X 4 behind it and use a tarchet tie down to the front forks or something.
Cool.
Buddha.

Priceless! That ratchet tie seems an excellent idea!
Thanks! Will post news...

Too soon to set it on fire. But it's an idea afterall... 

Ive seen those videos, that procedure is very similar to an F4. Although in those videos, one can't see the part where he actually pull the carbs. When you see him pulling it, there is already rags at the intakes. I'm 99.9% sure that my procedure is right, but those rubber boots are so dry and stuck that they appear more like molded plastic than rubber. One possibility will be cutting them!

About the ratchet strap...just found out there is no place that I can attach it! The whole engine is at an angle, the boots are at a 90º angle from any metal part in the bike, so I would be pushing them sideways instead of lifting them. Smart approach but I think it won't work in this situation, does it?
I've been told that a air dryer or heat gun will also help. So till now, I've got: Lube, heat, lube, more heat, Crowbar?! Any suggestion? Warnings?

I think virago = viagra.
I have 1 small twist there. A 1100 virago has a drain bolt in the float bowl, you can remove and clean and replace the main jet and if you have the right size wire, bend it and wiggle it into the pilot jet and clean it too.
But getting the carbs out = nightmare.
Cool.

You know, the way the carbs are, at that angle, I can take out the float bowls reach the jets and the vaccum chamber. But it became a proud issue, man vs machine. If I can't tame it, I can't ride it.
Here are some pics:








As you see, a small screwdriver is all what I need to get the bowls out, but no way I will surrender!! 

EDIT: I've not taken these pics, I found then in the internet just for illustrative proposes!

make sure you got both clamps, on the carb side and on the intake side.  I've never personally worked on an f4 but the f3 I had was a pain in the shaZam as the boots were not letting go.  I use a handled prybar to 'gently' pry on them, rock them back and forth, or try to pick up the whole bike using only the carbs.  Lube you already got, so I'm thinking you'll just have to keep at it.  If those boots are that dry, you might replace them anyways,...exacto to the rescue?  Good luck.  I hope you keep posting pics of what you're doing.

Your bike has the F4i tail on it! take it back to the dealership an tell them you want the fuel injectors put in!

[piresito]

And out they are!! 



I've used and air dryers, tons of WD40, two ratchet ties and two big wrenches. I've put pressure in it with the ties, then lubed, heated, lubed, a bit of pry each side, more tension (up the point the ratchet mechanism started to get warped), then I started to pry with the wrenches on each side and the carbs popped! Really popped like an Champagne bottle cap!! At first I though "Cool..." then I though, "Oops...from the sound I must have wrecked something"...but no, it's a Honda! 

Now, the boots are a bit dry, and some of the inner tabs have ripped, in the red marks:







I think that those inner tabs are not needed for an air tight junction, as the clamps press the boots so tight that there is now way a molecule pass trough there, I think. But hey, I never had experience with air leaks.
There is one other problem, I've checked the boots prices...30€ each, thats like 40$, each!! After a second search I've seen them at 12$ each, less problemtic...

What's you opinion for this? Do I really need to get new boots, or it might work with these?



BTW, those pics in my previous post are not mine. They are from the internet, found them in a thread for CCT replacement!

Yup brute force is the best ... why dont you try a stick of dynomite next time.

I though about that, but didn't have any around...

getting the fuckers out was easy, getting the fuckers back in was the Buddha Loves You. i dropped a bolt down INTO the intake. i got lucky. after drinking 6 beers to calm down. pulled plug, and used a telescoping magnet, and fished hte screw out

Hi!
Valves adjusted (shim under bucket shaZam!!!), carbs clean and it's time to get them back in the engine...any tips?


P.S: I don't have a Sledgehammer around.
