Thanks

That's why I need some clarification. The genuine manual for the Z1, A's & B's gives that precise way of checking them. However, for the A4's and/or engine No 18866 on they give the revised procedure by aligning the marks on the individual cam sprockets such that you can do valves 1 & 3 an 2...

Engine No: 115055 Clarification on valve clearance check. With the lines on the appropriate camshaft aligned with the cly hd you can check the clearances on No's 1 & 3 or 2 & 4. So in that case the relative lobes will be in different positions, see attached, is that correct position for both...

Is there somewhere where you can get a full set of st/st hoses for a 76 Z900A4 with twin disc? I am looking for a set on which all the banjos and the inline connectors from the flex hose to solid pipe connectors are also st/st. Can somebody advise what that connector type is and what the thread is f...

Has anybody got a spare mirror plastic cover, as used on the Z900A4, or complete mirror and cover as in attached photos, in good condition? I believe that they are original design, if not what are they? Existing cover has several splits, so I only need the cover but happy for mirror and cover if ava...

Yes you are absolutely right, should be No 1 on left and No 4 on right. Very much my own opinion that the air filter in or out does not seem to make much difference. As I indicated I have previously swapped all jets, main, pilot and emulsion tubes between No 3 & 4 and it has made no difference, ...

Took the bike out again today on which the No 3 carb has had the needle dropped by one groove. Air screw on No 3 set two turns out to weaken the mixture even though it colourtuned around 1 1/2 turns out. Plugs are No 1 to right to No 4 on left. 1st photo done with 60mph chop and is with air filter f...

Thanks for info about the plug taken at Donnington. I have been away with some friends on bikes for the last few days and now back, so subject to the weather I need to get out and try the bike now that I have dropped the needle by one groove on the No 3 carb to see what impact, if any it has? Will r...

Plugs of No 3 and No 4 were swapped as I do not have the ability to thoroughly clean plugs, nor a new supply to keep changing every time I do a test. So I cleaned No 3 as best I could and put it into No 4 and moved No 4 to No 3, which is why it probably looks so bad, all pots were firing OK. Have dr...

I'm still hoping it is a carb issue as anything else will be a pain in the butt. Transferred all the jets, seat, valve, float pivot pin and float from No 4 to No 3 and all of No's 3 to No 4. However, I also fitted a new float to No 4 which went it without any tang adjustment. Did another plug chop a...

Andy, when you did the engine rebuild is there any chance you might have accidentally fitted the oil ring expander with the ends overlapped restricting the oil scraper rings from being able to expand to the bore size? It wouldnt affect compression but would definately cause a black plug. It doesn't...

The VM26SS cards, I believe, do not have the half shims that you refer to. Will look to drop the needle by one grove over the week end and remove the air filter and do another plug chop at around 60mph, but remember to take my camera with me. The problem with the No 3 is that with the amount of carb...

Photo of plugs was before I removed the carbs, cleaned them replaced the seat/valves, had the choke plunges done etc, only No 3 now remains black and sooty. Another photo of the 'now' situation would allow a better assessment of the many changes that have happened since that photo was taken. In the...

So long as the slide moves freely and doesn't have any chatter, then it's not essential.

Thanks, assuming I am actually able to find a No 3 body/carb?

There is little to zero chance of anything being structurally wrong with the carb body unless something like the emulsion tube has been overtightened and caused a fracture in the casting allowing fuel to seep through. There are three fuel paths in these carbs and if the jetting and needle heights e...
