Carb strip

[harri183]

Undertaking a carb strip and clean and just wanted some advice. Z1100r fuel pissing out of left middle carb, due to the age of these things and the fact I will have it in bits do you recommend replacing any of the parts for preventative maintenance or just clean and put back together, also could you recommend a place to get quality parts from as I can imagine some of eBay may not be up to standard. Cheers

O rings and gaskets only assuming the jets needles valves are genuine. Clean the original parts, carb kits are generally the cause of more trouble than they are worth.

Clean and put back together using original parts unless you fund something that is damaged. Then preferably replace with genuine parts if you can find them. Don't replace genuine parts with aftermarket unless you have a good reason why.

Many people on here have used keyster carb kits and are quite happy with them. I'm not so convinced personally, but the gaskets seem ok. O rings are the biggest pain as they have to be quite accurate and aftermarket ones often aren't.

Hopefully you'll just find that there is some crud (likely rust out of the tank) stopping the offending float seating properly and that'll be it. I have had success with getting the float needle valves to seat properly by putting a very small amount of diamond valve grinding paste on the needle, putting it in the seat and rotating it a couple of turns to lap it in slightly. Go gently as the seat is very soft. Thinking about it, toothpaste (usually contains fine abrasive particles) might work and be a bit more gentle.

Cheers, always best to ask before you dive in and cause more problems than you started with.

As above.
No need to replace any original brass internals unless they are physically damaged.
The flooding will most likely be the float valve which may just need a clean out and lapping with toothpaste.
The parts to replace would be Gaskets, 'O' rings, float valve , choke plunger seats and possibly the slide diaphragms if split or perished.
If you have to replace any brass internals then use genuine Mikuni .
If you must use pattern then Keyster are the only parts i would use.
I have used entire Keyster kits in bare carb bodies when changing the spec in my bored out VM's and they have worked perfectly.

Cheers, were is best to get hold of the parts seem to be limited for the 1100.

Where do I get the key star kits from for the z1100r, seen the float valve kits on eBay but need the emulsion tube as little bit of damage on it. Really struggling to find parts for it. Do I need to look at different models such as z1000R or z1000j? Can’t find a kit for it. Cheers

Bought all my CV bits from one of the best known suppliers. They claimed that they were; manufactured by them or for them to the same standard and spec as genuine Mikuni parts. Not so. Float valves were too short and float bowl gaskets too big. Couldnt set float levels correctly and floats rubbed on gaskets and stopped them moving freely!!! That was a while back. Since then i have had good results with Motocarb who are a Mikuni (see other spellings) distributor.

As with all these things; parts are very specific and differences tiny so the more information you can provide them with the greater i would say would be youre chances of success.

That’s the problem it’s like the blind leading the blind. Cheers
