26mm carbs

[ash]

Whos got a picture of the underneath insides of a set of 26mm carbs, mine dont seem right for some reason,

[Garn 1]

Ash, sorry no picture as yet!
What you are probably looking at is the difference in the Air/fuel screw adjustments. The later Mikuni 26mm carbs had a fuel adjustment screw at the bottom closest to the head, whereas, the earlier carbs had the short spring loaded Pilot air adjustment on the top.

RegardZ.

Garn i will put a picture on later then you can see, not got a manual to do any references, mine should have the later 32mm cvs on them but the bike came with the 26s, theres no main jet thats for sure, and the only air screw from what i can see is on the top, little brass screws that sit offset either side of the carb bodies, i do know from the past that some of these carbs had a 1.5 or 1.7 idle jets, these dont have them either,

Garn heres some pics of my carbs, see what you make of them,

no pilot jets, mains or emulsion tubes in there !

try nrp carbs.................

[ash]

Chrisu just what i thought, now if anyone has any i,ll buy them off um,

[chrisu]

they're not A4 carbs though.................

only a single fuel feed and A4s have 2 feeds - to left/right bank of carbs.

[ash]

Dont know the setp up with the 26s so if anyone does let me know,
I,ll be running filters so i can judge from there what main jets to go for,

[ash]

Chrisu single feed with vacum pipe to tap,

[chrisu]

z1000 then............... probably A2 given the vaccum takeoff on the fuel tap.

i'm sure someone more knowledgeable than me will be along to recommend main jet size uplift.........

[kev edwards]

Looking at the ribs on the slide housing tells me the are 650 carbs, i've never seen ribbed on 900s or thous.

[ash]

Yes they are z650 carbs off my z650,

[ash]

Kev seeing as i aint got a manual i just need the spec , eg main jet, idle jet size and whether anyone on here have the parts i need

[Crofty]

ash, they are 24mm 650 carbs, you were asking about 26mm carbs as fitted to Z900A4 etc
I think I might have some emulsion tubes and mains etc, pm me if you need me to check.
Thought you were doing webers?? or maybe your thinking of going to 26mm in future. I'm like jimmock, confused

btw they look to be reasonably clean inside and also they did a 22mm version with ribs on as well, but not on many models of 650

[ash]

Sorry thought the 650s had 26s seeing as mine suppose to have 32mm cvs as standard,
Pm sent mate
Forgot to say, the manifold dosent fit the 650 head so its a no no on that at the moment, holes are out of line by a long way, unless i can get some adapter plates made im gonna leave it for now,
