Hi, don't know if this has been covered, sorry if it has... so, after taking off and putting the carbs on my '79 CB650 about 10 times... the 11th time I did this... getting them on without swearing... my usual bear hug on the motor was not necessary...

I used a one piece length of nylon rope and carefully wrapped it around the carb backing plate between carbs, in a loop towards the front of the motor, then ran it over to the other side making another loop around the carb backing plate again (my explanation might not be the best..hopefully this will come across in the pics)... make sure you haven't pinched anything, I then put a piece of wood in the loop at the front and twisted, slowly tightening the rope, make sure you're not doing any damage to your cooling fins (I went under the head), wiggle your carbs a bit, keep twisting... POP!... they went back on!! no swearing, no sweating.

Ratchet straps also work, and a heat gun helps a lot.

Step 5) Make sure your thumb is out of the way of said piece of wood... HA

True, that's a good idea! I don't have'em though.... got to get me a set o ratchet straps, I just have the reg kind. I also read that wintergreen really softens up those boots... I don't know if we have that in Canada... never seen it before..

Interesting trick.

I got mine back on this last Sunday with spit and about a 4ft 2x4 - knee on one side, one hand reached over on the other end of the board and one up top around the handle bars. Pushed them on.

Never used wintergreen myself, but I know a lot of people that swear by it. I'm going to have to give it a try for the heck of it some day.

Heat gun and a couple of ratchet straps should run you less than $20 at Harbor Freight - and since you're not actually relying on the straps to secure a load in a truck or anything, the Harbor Freight price over quality policy works in your favor.

The wintergreen oil and xylene treatment is great. Works wonders softening old rubber. There are a few threads on here about it.

Good idea. What I did, after a lot of cussin', I sprayed some dry film lubricant on my finger and then wiped the inside edge of the carb boots. aligned them up and pressed them on.Yes it still took pressure, but went on easy. No more cussin'.

Heat gun and silcon spray works well

I soften my boots and put my carbs on easily. No 2' x 4's. ropes, rachet straps etc. They push right in and seal nicely with no air leaks.

After taking my carbs off and putting them back on more times than I'd like to think about, I tried the ratchet strap idea. I took two of the small width (1-1/2" wide) straps and carefully routed them through the carb rack on each side. I took some 3-in-1 Oil and lightly oiled the barrel of the carbs and the carb boots. I made sure the carb barrels were lined up with the boots and then I slowy tightened the ratchet straps evenly on each side. This method worked like a charm!!! I was able to get all of the boots on evenly and then tighten the clamps without worrying about the carb assembly slipping. Great idea!

Did the wintergreen oil thing on the carb boots. They slid on the intake things snug but doable by hand. The carbs still relied on a bit of spit and a 2x4 so I can work them on. One thing I did notice with the wintergreen oil treat is that they also swelled a bit longways. So, it was a little tight getting the airbox mouted to the frame with the upper two bolts.

When I left mine in the Wintergreen Oil for longer than overnight my boot had swollen as well. After a couple day they had gone back to the original size and were still pretty soft.

The boots to the air cleaner on my F1 were so hard I thought they were made of plastic instead of rubber. Overnight in the Wintergreen Oil/Toluene mixture and I could roll them into a ball the size of a quarter and have them spring back into shape.

Did make reassembly much easier.

I was lookin to thank the guy who said to use a broom stick to take thhem off and put them on. It would have gone better with a little oil. This is my first 400f. I got the carbs off, cleaned and put in carb kits, put them back on with the broom stick and the bike fired right up. Awesome and thank you for all your handy tricks everybody.

This method saved me a ton of headache i got frustrated came online read this quick and had the carbs on in like 5min after fighting with them for about 30 minutes. i did it a little different i ran the rope around the back of all the carbs then thru the top fin on the engine and around the frame rails i used a rear brake strut to tighten the rope

Geeezzz.........I must have been one lucky dude..............................

Have a 350f and a 750k and had the carbs off of both bikes, and they slide right back on.

The hardest part for me was getting the air box boots on.

Tightening a loop of rope by putting a stick through the loop is called a "Spanish Windlass" Sailors developed that method to tighten lines. It can and has been used for many things.
