#1:  removing the carburetors Author: motormouse Post Posted: Sun Mar 25, 2007 10:22 pm

A lot of people have written in asking how to get the carburetors out of their 700/750/1000/1100 Viragos. I have only done it on bikes with Mikunis and made after 1987, but the process should be the same,at least for 1984 and up.
I won't go into how to remove the air cleaner or the AIS. This should be fairly simple.

You will need to remove the seat and tank.

After that, you will remove the rubber intake boots. They are held in with two hose clamps.

Then remove the throttle cables and choke cable.

The next thing to do is to loosen ( do not remove) the inside bolt for the rear cylinder flange.

For this, I use a 10mm wrench that I bent at a slight angle to get the clearance I needed.

next, remove the outside bolt from the rear flange.

Loosen the collar clamp for the front cylinder flange and gently pry the carburetor back until it pops free from the flange.

If you have a 1000 or 1100, remove the hoses from the front flange.

Next, loosen the inner bolt for the front flange (again, do not remove it).

Then remove the outside bolt and slide the flange out.

We are almost done!
Push the carburetors to the left to free them from the rear flange bolt and tilt them forward.

The next step I do is to thread the rear inside bolt all the way back in to give myself more clearance.

Finally, I slide the carburetors out to the left and remove them from the bike.

Now there is a big hole where the carbs used to be!!
(Reverse the order to replace them.)

Nice presentation motormouse!!!

motormouse: what a great set of photographs and presentation. the yamaha dealership here took his 10mm and ground it down to become flatter and of course bent it just like yours. i replaced the bolts with hex heads . and yes its the same method of removal as the 84 hitachis, yamaguzzi-*

Very nice work motormouse.

#16:   Author: funkamongus Post Posted: Sat Jan 17, 2009 12:50 am

Ditto, I did the very same with the exception of taking the inner bolts out and leaving the left side elbow hanging and sort of hooked up. (mostly to remind me where things go!).. VERY nice presentation!! Bravo!!

PS a 12 sided box end wrench and some patience worked fine for me with no mods to the wrench.
