Thanks guys...

Well, i couldn't just leave it again in the shed without trying to ride her.
The clutch is activated on the left side by a worm drive arrangement and a rod that goes through to the clutch side.  Some may remember that whenever the chain was dropped, it would bend the rod and you would have no clutch.

Anyway, i found all the bits in boxes and got all that side of it working.. but the clutch plates themselves were seized together.  So, drop the oil, rip the cover off, pull the clutch and clean and soak it all.
Got the clutch all working well... Next stop, find chain, front sprocket, nuts etc.. rebuild a chain tensioner and prepare the bike for launch.

It was getting dark, the kids were getting hungry and i had tools flying around the workshop... this was a mission..

There are no brakes fitted and no footpegs.  I just wanted to see if the tranny, clutch and motor would work.  I fired her up, pulled the clutch in, selected first and took off up the street.  The 78 had a 5 speed box, so in my boardies and Crocs i get her up into 5th on my street as darkness descended.
Never thought i would see this thing running.  But the old Yammies are indistructable, and this one has a smooth gearbox and clutch.  Motor run OK too.

I put her back in the shed with a grin on my face.  This one is now ready to start a full rebuild.



Cheers,
