So the carbs from E-bay turned up.
https://i491.photobucket.com/albums/rr279/bladeblaster/12141082_10153182941204013_1468178551592066076_o_zpsqz9sgagl.jpg
Only to find that the butterflies are fairly seized, but not sure why. So I get to stripping them down.
Then I find that 2 idle mixture screws are missing and the 2 that are there are both knackered. Managed to get one out, the other one has no chance.
So I go to plan D
I only really need the one body, so I can take the body I need and swap it with the broken body on the other set.
So I start breaking down the bank, most of the screws holding the back together are seized or already rounded off, but hopefully in here somewhere is one good set of carbs.

Took the bank to work and drilled off the screw heads on the pillar drill, separated them, only to find that the body I need is the one with the seized butterfly
So 8 carb bodies, and no 1 good full set
So plan E a full set of A1/A2 carbs came up on ebay so I have bought those. Should arrive today, they had better be good. |

I'm glad I didn't go to all this trouble with my GPz project.... but then I'm also slightly disappointed
I haven't really had the need to strip carbs down to individual pods, so I'll admit I haven't got a clue what I'm talking about here.... but aren't they all the same when EVERYTHING is stripped from them? Or at least in pairs anyway?
Also with the screws on my carbs, they were big enough to get a set of needle nosed mole grips on there to crack them, had to replace all the bottom ones because they were all rounded etc, the top ones I didn't even bother putting much force in to the screwdriver before going for the mole grips again |

Thank you OP, you've saved me thousands of pounds and a shedload of grief - your posts have cured me of the notion that I could one day restore a bike. I don't have the skills or patience and my 'workshop' is unbolting parts in the street and cleaning them in the kitchen. ____________________ Current bike: K1100RS.

That's impressive. But I don't have a driveway. I suppose I could designate a corner of the bathroom as a motorcycle mess. ____________________ Current bike: K1100RS.

Those butterfly valves...........I was reading about a tool to help get them off the other day so don't abandon hope. I'll have a look for it.................
Do you have close up pics?
If they're screws...and you've rounded them off.......you're not the first ____________________ Space Is Deep |

Time for a Carb Saga update.
Repeated application of penetrating fluid did free up the stuck butterfly quite well in the end.
The new carbs looked really good when they arrived, so good I was considering bolting them straight on. However I didn't and I am glad I didn't, the insides we covered in rusty coloured fuel residue. Worse than that all 4 idle adjuster screws were missing their o-ring seals. The ends of teh adjusters were black as hell, must have run as lean as an anorexic bacon sandwich.
So new set stripped & cleaned, I had new idle adjuster seals that I had already bought so that wasn't a problem. So once all cleaned out, time to re-assemble.
Bottom end:-
Vernier set to 17mm to check float heights
https://i491.photobucket.com/albums/rr279/bladeblaster/12112217_10153196568834013_4964418979589696153_n_zpsqzasasar.jpg
Floats & Shut Off Valve in, first checking that the rubber pointy end is in good nick, and the spring on top of the valve is strong & moves freely.
https://i491.photobucket.com/albums/rr279/bladeblaster/12108232_10153196568419013_3674561498513765901_n_zpst7ubzzpe.jpg
Check float height, this one was low as you can see by the gap between the top of the float and the bottom of the vernier body.
https://i491.photobucket.com/albums/rr279/bladeblaster/11222547_10153196568829013_2153848052827561133_o_zpsiqqamwka.jpg
So adjust by bending the small metal tab that the float hangs off, one way or another. Low float means the tab needs bending towards the float. Its a trial and error amount, not an exact science, just keep re-fitting & checking until you get this. The float needs to be sat just on top of the valve without compressing the spring on top of the valve, when you take the measurement.

Now back in with the various jets:-
Needle Jet
https://i491.photobucket.com/albums/rr279/bladeblaster/11167656_10153196568814013_1465843608683305132_n_zpsq4wuxamc.jpg
Emulsion Tube
https://i491.photobucket.com/albums/rr279/bladeblaster/12115559_10153196568809013_4023030134465796180_n_zpsbuezajnc.jpg
Main Jet
https://i491.photobucket.com/albums/rr279/bladeblaster/12107261_10153196569024013_1117731871199962690_n_zpsykmi5gse.jpg
Pilot Jet
https://i491.photobucket.com/albums/rr279/bladeblaster/1470113_10153196569014013_1377343245997196888_n_zpsidd59egw.jpg
Pilot Adjustment Screw, properly assembled with o-ring seal.
https://i491.photobucket.com/albums/rr279/bladeblaster/12118957_10153196569019013_5542635927046347486_n_zpss1arpti0.jpg
New seal in the float bowl.
https://i491.photobucket.com/albums/rr279/bladeblaster/12095216_10153196569009013_2536180955551177679_o_zpsqnwjwinw.jpg
Now for the top end.
Little bit of Rubber Grease to help the diaphragms seat properly.
https://i491.photobucket.com/albums/rr279/bladeblaster/887479_10153196568459013_9044056090785655878_o_zps8sbz5fsx.jpg
Diaphragm & slide back in, and top face greased.
https://i491.photobucket.com/albums/rr279/bladeblaster/12113291_10153196568439013_2167408889080786081_o_zpsbyvyqd13.jpg
Main Needle In.
https://i491.photobucket.com/albums/rr279/bladeblaster/12095106_10153196568424013_4499037246402542073_o%201_zpsvqe0uhfh.jpg
Spring seat & Spring in, taking care not to black the vacuum port with the spring seat. It has to sit with the legs either side of the hole, if its positioned with a leg blocking the hole, it knackers up the vacuum, and it will never fuel properly.
https://i491.photobucket.com/albums/rr279/bladeblaster/12095278_10153196568454013_19244337403836481_o_zpsyqshbkrr.jpg
Then tops on, and all back together, with nice new cap heads & spring washers.
https://i491.photobucket.com/albums/rr279/bladeblaster/11223925_10153196562389013_1989842155309956333_o_zpszcwbcmaw.jpg |

Thanks mate for a decent thread - it's amazing the amount of wear and tear a motorcycle is subjected to - fantastic you have the ability to fault find and repair - I doubt any dealer could have done better - well done that man - fancy changing my belt and rollers |

A very frustrating weekend on the GPZ
The good news, the rear shock is in.
https://i491.photobucket.com/albums/rr279/bladeblaster/12814712_10153455965669013_5885533068047598212_n_zpsdtisqvx5.jpg
The bad news, I thought I had the circlips for the tie rods, but I didn't so I couldn't finish fitting it, needs circlips fitting then everything torqued up.
More good news, the front lines are fitted.
https://i491.photobucket.com/albums/rr279/bladeblaster/12186233_10153455997439013_5213086437354038805_o_zpsqtnpvuyr.jpg
The bad news, the reservoir screws were so chewed up they are unusable, so need new ones before I re-fill the system. So couldn't finish that job either.
To top it off tried starting her again, and come to the conclusion that the starter clutch really is totally shot, so the engine is going to have to come out after all. I know I knew but after the false hope it gave me early on, it feels like a bit of a kick in the balls.
1 step forward and 2 steps back, definitely a weekend where you question the sanity of owning a 30+ year old bike, and wanting to take a match to it |

Bit of a shitter with the starter clutch but it will be worth it in the end... easy for me to say as I'm not the one that has to do it
