Question Noobie Q: Any tips for last stage of carb removal?

Hey All

Am removing my carbs and have done all advised in the service manual and haynes for the bike...

float bowls drained

air box casing all removed

breather pipes disconnected

the clamps are all nice and loose on both engine intake stubs and carb sides

fuel line disconnected at the union

choke and throttle cables disconnected

rubber bellmouth alloy part removed (sorry unsure of its name )

So I've got to the stage where you are supposed to pull the carbs from the rubber boots and I've been trying to wriggle the things out but after a few mins I've stopped cos I don't wanna force anything cos I love my dirty old bike to bits.

Probably the rubber boots have been on so long that they don't wanna give up the game just yet. There's some movement but it seems to be at the engine intake side.

Should/ can the carbs come off without the rubber boots coming with them?
I mean should the boots stay on the engine air intake side when the carbs come off (the pic in the haynes manual suggests so)?

If you've got any advice on how you've pulled the carbs at this point when they're being stubborn I'd really appreciate it.

Thanks guys

use a flathead and push them off the engine. they will come off, try heat and penetrating oil.

just keep working at them!

It might help if you try rocking the carb assembly front to back while trying to spray some lubricant into the boots. Just keep working it back & forth and pry against a solid part that isn't going to break off. They can be a real PITA to get off with the old boots.. mine got to the point I was worried about breaking something trying to remove them so I bought a new set of boots on Ebay. Not sure how easy they are to find out there, but there is an Ebay seller here in the US that has them for a good price.

Hey trippman and tahoerider thanks for your replies: a plan is beginning to develop in my mind...use the wife's hairdryer on the boots, followed by lube and leverage (might try a short length of 1 x 2) and a boat load of patience!

Cheers guys!

On a side note, if they are that hard to get off, it will take even more patience to get them back on.

Haha, x 100

I keep the aluminum part on and use it for leverage when rocking them out. Just a thought?

Hi guys

went back to the job the next day and they came out pretty easily with an old piece of wood and plenty of lube. oh and of course I'd removed the engine first

Cheers again for your tips
