Re: 1977 Z1000 Rear Master Cylinder O Ring

Thanks Kev, much appreciated. That's good to know. I also feel I could lock up the back wheel on the Zephyr as well. Quite surprising when generally these days you hear how average modern rear brakes are considered. Rear brake on my A2 (& previously owned Z1R) will overwhelm the rear tyre if use...

1977 Z1000 Rear Master Cylinder O Ring

Hello all I am looking at refurbishing the rear brake cylinder on my Z1000 A1. I found a couple of good videos (American) on you tube, one where the chap replaces the square section O-ring between the main body and the plastic reservoir. Would anyone have any links for the O-ring in the UK? I've had...

Re: Z1000st

Blocked pilot jets are typical. I always drain my carbs after every run as I never know when I'm going out next on the bike. Ethanol, say no more.

Re: Hyvo cam chain observation

Without being pedantic; Hyvo '''sprockets''' are closer to the definition of cogs than that of sprockets. The chains' contact area is spread across the face of the tooth and to qualify for the lofty title of 'Silent Chain', no parts contact that are not needed to make contact. This is partly achiev...

Re: Hyvo cam chain observation

Do the gaps disappear if you apply pressure on the chain between the sprockets like the slipper plate does? Your not comparing with the chain in the running position. Hi Warren, Thanks for your reply No there is no change when I apply pressure to the chain. Oddly when viewed from any other angle th...

Hyvo cam chain observation

Hello all I am checking the valve shim gaps on my Zephyr 750 and noticed the the Hyvo cam chain is sitting in a raised position on the sprockets. You can see daylight in the wells of the teeth in the first photo. I did a search of the forum and also found a photo by z1000puddin Which has the same ga...

Starter clutch upgrade

Hi, this starter clutch upgrade from Centurion Motorcycles on Facebook looks interesting and may help somebody. I've been a member for a while now, but don't recall there being any particular issues with the Z900/1000 starter clutches popping up on the forum? https://www.facebook.com/share/p/1BQZ5N5...

Z1000a1 Alternator Rotor

Hello all, I've just noticed that the outer body of the rotor is slightly loose on the inner that it is attached to. In frustration I've put some centre punch dings in it to firm it up. Having slept on it is guess this isn't going to hold it in place for very long? I see ZPOWER sell solid new ones, ...

As long as everything functions ok you don't need a jetting change from stock just for the pipe.


That's good news.

Re: Z1000 A1 Carb Jetting

Apologies for jumping in, but my A1 also came with a 4 into 1 (marshall) but with a standard air box.
Is there anything I need to know carb wise?

Thanks

Re: Inox Fasteners-Southampton

Thanks z1bman. That is one busy website :shock: I can only see domed hex heads in imperial, but I'll keep a look out in case they add metric sizes.
