Really sorry to hear your very sad news Dave -

That bike has always been absolutely immaculate - Someone could get a bargain

I think this is Keith's diagram - "a picture paints a thousand words"
And gives another name for the screw as 'pilot screw'

Carbs on my 1978 A2 have a screw mounted centrally and underneath the carb. This is a fuel screw, but confusingly referred to in the Kawasaki manual as a mixture screw. On my bike they have to be 1 1/4 turns out or it will not pull cleanly, My 1978 Z1r was different as it had an air screw in the sid...

Great pictures - I would love to borrow the Laverda for a week or two! - A mate of mine had a Laverda a few years ago but found the Mirage's reversed brake - gear change controls tricky to get used to. Some very cool bikes there.

I had an issue similar to this a few years ago on a z1000. I changed the points for a different set and all was well. I think it was said at the time that sometimes non original points sets can cause problems in setting up timing.

Lovely bike - suits that exhaust.

Probably a lot of us should ride them more than we do - inspired me to go out today and get some miles in - Shame to waste the sunny weather!

Nice pics of how it was 'back in the day' !

Wow - now you're talking!

When I lived in North Manchester I took a ride up to Devils Bridge at Kirkby Lonsdale - which is a bit further south. Great looking bike and some fantastic roads up there.

Thanks for comments -
Hi Zapo !
I sold my KH400 in 1980 !
The S however is progressing since last year's session at Twistgrip motorcycles has improved things.
Still not 100% perfect for me.
If you want to meet for a coffee (maybe Abbots Bromley again?) I can bore you to death with the full story!

I wish I could say the pictures were taken as I pulled into my drive - but unfortunately not!

Very surprised at that - the M5 fitted absolutely perfect for the whole length.

Took the screw out of a disused green dyna coil and inserted a screw which I am pretty sure is m5. (KH400 switchgear screw) So you should be ok with m5 replacement - you should also use a split washer. For info the threaded section is about 8mm and the head of the screw is quite wide at about 9mm. D...

Not sure how relevant to the seat pan but Philippe made some observations about A1 & A2 seat differences here:
