Air filter/box removal (Spray carby cleaner)

[cahop]

So an update................it runs ........................like a tractor

I cleaned up the bottom end of the carbies, but for the life of me I was unable to get the top of the carbies off to take out the plunger, those screws are stuck! I got about 50% out using the tap the screw drive with the hammer trick but I rounded two screws and one was already rounded so looks like someone has had a stab at this in the past.

I was surprised just how fast i had the carbies back in the bike and the bike running.....took all of about 15mins! So now it runs (not smooth, but idles and revs) going to take the carbies out again and have a stab at getting the screws on the top of the carbies undone. I'm thinking vice-grips on the side of the screw head is the next option.

Also going to take out the spark plugs and give them a clean.

Now off to buy a battery so I don't have to keep running it off the battery pack I have.

Just because I know people love videos, tonight I will upload the one I took last night just after I had started it

Yep, you gotta get those top screws off to get the slide and needle out....only then can you get the emulsion tubes out...you must clean those.

Slot the screw heads with a Dermel and use a big ass flat blade screw driver (with a square shank) and a Cresent wrench to get them out.
Do not use any heat, you will melt your diaphragm rubbers...

Plan on replacing all the soft JIS screws with ss allen head cap screws, available at your local hardware store or at RPM

Carbs can be fun eh? As Pat mentioned the emulsion tubes etc really need to be checked. I put 4 new kits in when I did mine, here's a few photos in this thread of what I found. Admittedly the bike had been sitting for a few years to let the carbs get this bad.

But with everything cleaned properly, new components in they should run like new (or close to
it )

I like the idea of the liquid electrical tape for the tears X-Ray, how is that going still???

I have to go buy a 18mm spark plug socket........its always the one spark plug socket you don't have 

As much as im not looking forward to it, the carbies are coming back out to clean with actual carby cleaner...........given they came up not to bad with WD40, hopefully after cleaning with carby cleaner may get them to a point where no new parts are need to get running relatively nicely again.

This is all a very big learning experience, but it has been fun so far.

I did mine twice, with patience this time.
All the bits I cleaned with steel wool to get all the craps off and used oxy tip cleaning set to get the crap out of all holes. Steel wool cleaned the inside of bowl then washed all those bits in hot soapy water.
Don't forget to remove idle mixture screws, they are removed from the outside and need to come out, just checking how many turns they were out to start with, for when they go back in.
I didn't use steel wool on the slides.
Then carb cleaner in all passages in carb body, then compressed air to clean any residue out.
Syringe and hot soapy water through everything again then compressed air.
I have 4 New carb kits to go in mine when I get a chance but if you get stuck and need to use them and replace later , no worries, I forgot to order new Allen screws for carbs so I don't have any of those, sorry.

So far so good, although I have only put a few miles on these carbs since being rebuilt. After I have done 1000kms I'll pull the tops off and check the diaphragms to see how they are holding up.

JIS screws can go die a painful death............

Just ordered a JIS screw driver as I have got the top off one carby but the rest remained fast and I rounded 3 screw heads......this is just annoying

No more annoyance should be had is you get one of these: FJ11-12/XJ12/XJR13 S/S Screw & O-Ring Carburetor Kit

Then you will have all new screws and all of the o-rings to properly reseal your carbies.

so an update.

JIS screw driver arrived and......................its incredible what the right tool can do!!!!! I have all the screws from the carby tops undone and plan on cleaning the carbs tonight.

However in news that may disappoint a few, the works on this bike are now just to get it running and then put it up for sale. It was intended to get this bike running and on the road, however an opportunity to purchase a KZ650 presented itself and I jumped at it. I have always maintained a "1 in 1 out rule" for my garage so this means the FJ1100 must find its way to a new owner.

Hopefully get the carbies cleaned and in tonight and see if that makes it less "tractor-ish"
