That grey sludge in the bottom was probably not grinding type paste but well chewed up bits of alloy from anywhere, those chains and gears mush alloy up really well, ask Trigger about the 175 and 250 centrifugal oil filters! On looking the shells I would use again as long as you know which rod/hole they came from
Yes Bryan, I marked all the shells, valves, rockers etc on taking them out so I know where they belong.

I think the original question you posed somewhere near the beginning of this thread Julie about "how do people know what to do just from manuals" is answered after what you take on with something like this.

After training in this sphere as a few on here have done,  much of the experience then is added as they take on work that had variously involved failure,  mistreatment and any number of ways that owners have generally cocked up what started out as a well running bike.

A vocational degree course in failure. Workshops are never surprised at what lengths people go to in mucking things up. You've almost written a Haynes manual yourself on here regarding these engines,  probably two thirds still to go.

A proper nurse would have done the bloods and sent them to the lab. Poor bedside manner! :P
One day I'll have the time to restore it, not just talk and dream....

We should all be very proud of what we do to keep these old girls on the road, regardless of the simplicity or complexity of the task  :) :) :)

Not doing much to the bike today but have taken the clocks off to send away for a bit of a spruce up with nice new faces.

I thought I would have a closer look at the cam chain tensioner and assembly. The cam chain tensioner arm (horseshoe) is in excellent condition as shown in the photo yesterday but I will free off the very slight tightness I can feel on the pivot pin as Bryan suggested. The chain tensioner adjuster and the 2 tensioner outer springs are also in good condition so I will use them again along with the chain tensioner holder and dampers.

On the tensioner slipper I can see that the little tabs either side look a little moth eaten and on the guide, there are cracks all the way along its length. I’m going to fit a new slipper and guide anyway but interesting to see the cracks on the surface.

Having met both Julie and Trigger and noticed the glints in eyes the only thing that surprises me is that it isn't half back together already!! Honestly though this is well written and should be a great guide when finished, perhaps Steve could put it in tips when its done. I think the only 400 parts i have are the genuine manual and parts book on CD possibly a set of very bad carbs with broken bits unless i binned them as too bad!

Just read this from the start and as usual I am amazed at the punishment these bikes will take and still run, looking forward to more updates.

Cheers
