Carb removal
#1
Soooo, the day I get a phone call from someone looking to buy my bike I discovered the carbs are blocked because I haven't been able to ride the bike thanks to a broken shoulder.

I've tried looking for detailed instructions for removal of the carburetors as I have a specialist who can clean them but only if they are removed. 

The only instructions I've found are for the FZ1 which is quite different. Is removing the aibox as simple as losening the clamp and pushing back? 
Doesn't seem to be any room to move. Do I also need to replace anything like seals? I only had the carbs cleaned in 2023.

Ahh, I think I've worked it out, I misinterpreted the picture of the airbox and didn't realise how far back it went. Going off the Cartest software web pages.

Can also push the rubbers into the airbox to give much more space!

Quality seal kits available for sale here....

Ok, so I've managed to lossen or undo everything needed, but I can't free up the carbs from the engine collars. I've loosened all four so they can move but the carbs wont budge.
Any ideas?

Rubbers still got a grip on even with the clamps loose, not unusual. Will any of them twist - without twisting so hard you wreck the rubbers? Can you get a bit of wood in there to lever them off? If you have a hot air gun or a decent hair dryer to warm them might make them a bit more pliable. If you can get a small screwdriver down the side it might break the grip but again need care not to damage the rubbers.

Those rubbers aren't in the right place so will still be holding the carbs tight.

Under np circumstances should you need a block of wood or a spray of this and that followed by more screwdrivers...

They literally fall out once those clamps are loose and in the right place.

So what is the right place?

There are little nipples on the rubber inlets. As you push the clamps around you will feel them sit into place.

Looking at the photo you have posted, you need to push them under a little...

Biggest issue here is that if your struggling this much to get them off, you'll have heartache trying to get them back on.

The little nipples are important. I posted a video a while ago on FB about the importance of them, I'll try and find a link but its too big of a file to post on here.

To answer the original question, once the inlet clamps and the airbox clamps are loose, simply push/pull the carbs up and down while pulling backwards.

There's a ridge on the carb stubs which engages with a channel in the rubbers and a straight backwards pull isn't enough to break the carbs free.

Thanks Mike, I got it now, after some trial and error and help from Richard.
