Install The Carburetors On A 1986 Vfr 700

HOW DO I INSTALL THE CARBURETORS ON A 1986 VFR 700. I TOOK OF THE OLD CARBURETORS AND NOW I WANT TO INSTALL A NEW SET OF CARBURETORS , BUT I CAN NOT GET THEM TO LINE UP RIGHT WAY. I WOULD APPRECIATE ANY ADVICE.

You might find it's much easier if you replace the rubber boots between carbs and engine. Since the carbs point in two directions, those rubber boots need to flex quite a bit. They get stiff with age and it ends up taking a lot of force to twist things around and get things in.

Other than that, use a pry bar and plenty of silicone spray.

First of all, you may consider taking the rubber flanges off and getting them warm and soft in some hot water. Pay attention to how the rubbers are oriented if you do take them off. Use wd-40 and a little grease perhaps. Install the carbs in the front flanges first. I use a long 2x4 levered under the frame where the front of the tank mounts to put downward pressure on the rear/top of the carb assy to get the rears in. I usually get one side "started" and then switch to other side before the final push. Make sure to look at the rear flanges as the carbs go in to verify that they are not getting folded over and might tear.

It will look like there is no way the carbs will go in after you put the fronts in first, but they'll go.

Good luck!

Thanks for the info. One more question, should I put the rubber on the carbs or on the motor before I install them?

Motor. And, again, pay attention to how they are oriented. I'm pretty sure there are some arrows molded in the rubber to help.

Mine are getting pretty hard too, but if you just set them on the cylinder heads with about the top half on and just push straight down, it seemed to work

Go to my site and click on the How To link on the left. In there I have the procedure for removing and installing the carbs on a V4. Have fun!

Hair dryer works well to soften them up in place.

i was just wondering.. in your picture you have the carb boots there and the lips of them are on pointing twards you.. so when you instal them.. in the end should they be pointing out to the left and right of the bike..? as in i know the front 2 carbs and the back 2 carbs.. left pointing left and so forth....

about ten minutes in a pot of boiling water will soften them up long enough for you to get them on without a whole lot of fighting, but you gotta be quick.

best thing to do, get a new set. a new set will go on even easier.

its been a year and 1/2 since this question was asked...
sooo.. did you ever get them on? hows your bike running? :comp13:

Since the two front cylinders are pointing towards the back of the bike, and the two rear cylinders are pointing to the front, I set the boots on the lip so that they are more horizontal, so the outside lip of the boot is touching the shelf, but the inside of the boot is on the very top of the lip.
They shouldn't be pointing out to the right or left, all I'm trying to do is line up the front and back edges. Then when you push the carbs into place, they are wedged into place instead of trying to push the whole boot on at once. Sort of like when you try to fit a coolant hose on your radiator. Hope that makes sense...
