Re: irregular Idle 73 Z1

Most common cause of hanging idle is incorrect cable adjustment (especially too tight on the pull) which does give the symptoms you mention so that is the first thing to check There must be a small amount of slack in each cable to ensure they are not pulling against each other at rest. If rolling th...

Re: Carb adjustment query

Ah ZED1015, I think you've just solved my problem, and I'll sleep better tonight!! :D So, the manual page I put in the first post, just under the diagram B21, when it says "Turn the adjusting screw to make a slight clearance between the throttle valve and the bottom of the bore" it means ...

Re: Carb adjustment query

Ta for the reply Zed1015. If I start with the adjuster screws turned in so the lock nuts can do their work, the gap decreases and the wire won't fit in. The adjuster screws control the gap. No! The adjuster screws only adjust the slides in relation to each other. It is the idle screw that runs on t...

Re: Carb adjustment query

You need to start with the adjuster screws turned a few more threads in so that the top of the larger thread is below the surface before you start and then level the slides with the wire method and make sure you only turn the screws clockwise from their initial position. That way the nut and washer ...

Re: Carb adjustment query

You use the wire method on the lowest part of the slide which is closest to the engine (opposite the airbox) but it is only to get all the slides at the same height in relation to each other for initial set up or bench syncing. Once done the idle should be adjusted on the idle screw and at this poin...

Re: Gear shaft

Hi Tony I don't want to steal your dream but the gear shaft of an ST is not the same as the one of a MK2. They have different numbers and they look different! Other parts of the gear shifting mechanism are different too! Gear shaft ST: 13161-1011 Gear shaft MK2: 13161-029 Take a look at the parts o...

Re: Z1000A1 carb setup

All I have is the needle and clip sitting inside the slide with the lifter sitting over it. The needle isn’t well retained and can float up and down about 1/2 - 1 mm, which don’t seem right. Can anyone tell me what’s supposed to be in there? Thanks, Olly Just the Needle and clip is correct. Nothing...

Re: Buckets

They look pretty much normal .
Contaminents and particles in the oil due to infrequent oil changes will cause the scoring and also if parts have been media blasted and not thorougly cleaned before assembly.

Re: Measure bore diameter without strip-down - is it possible?

If the pistons are clean enough you may be able to stick a camera down the plug hole to read any markings on the piston crown or you could CC the cylinder and subtract the combustion chamber volume to find the capacity. Other than that there is no special tool that fits through the plug hole and the...

Re: Z1000A1 carb setup

If you need some air corrector jets I still have some sets for sale here via PM or from my ebay listing BUT I doubt you need any as they are to correct the LEAN condition off idle caused by the use of open carbs or high flow filters. Just removing the snorkel from the airbox but still using a filter...

Re: 1973 Z1-NOISE IN MOTOR

To help isolate the noise you need to have the bike stationary but running and in gear with the clutch disengaged. This will prevent any gearbox components from rotating. If the noise disappears it's gearbox related and if not then you know to look at the crank etc. I would check that the starter mo...

Re: Yoke material

They are cast STEEL.
You can weld via Gas, Mig. Tig or Arc.
Probably best to use ARC in short bursts to build up a new stop.
