Hi. Are you selling off the bits you don't want to help fund it. If you are can I have first dibs on the exhaust headers. I fully restored one of these a few years ago and at 14000  miles the head will be ready for a rebuild, specifically the exhaust valve guides. Sorry to sound mercenary about the exhaust but you have to get in quick on here. Good luck with the build.

Looks like that will keep you off the streets for quite some time, it's good that you are taking lots of photos, I found it handy when reassembling, especially for cable and wiring runs.

Cheers

With front and back ends off, we just about managed. Made a harness for the front to take the weight, with second person steering from the frame rails at the back. Damned heavy.. my back is aching...but we did it. These things are VERY heavy. Will get a sack truck for next time.

Next job is to get the engine out. I have made a cradle out of scrap wood so I can roll the frame over...and lift it off. Then I have a stretcher frame to move the engine so I can get it in the shed and on the bench. Once I have recovered..

As far as mileage goes...I am pretty sure the Speedo is not original, so I am assuming high mileage...and expecting at least a tip end overhaul. Plus..can gain tensioner, guides etc.

Better that way I think. Pessimists only get nice surprises. Optimists set themselves up for disappointment......

Nice surprise 1...
The forks dropped out if the yokes nice and clean, with no suspicious tight spots. A sign of straightness. Chrome is amazingly good. I have got bikes through MOTs with worse. 

Nice surprise 2..
The headstock was nice and tidy with no I ovalling, and the bearings had been greased. And the castle but had never seen a hammer and screwdriver.   

Today's odd find.   
Something looked to have been welded on the frame behind the tank mounts at some point, either side of the centre top tube. Then removed and painted over. Thought it was damage until I realised it was on both sides and symmetrical. Wonder what was there... 

Now...my surplus parts...
I probably will be selling on the bits I don't need to help buy the bits I do. Not immediately, just in case plans change...but as soon as I have a replacement part paid for. But drop me a message on the headers and I will give you first refusal when  I sell. Going to cut off the remnant of tail pipe as the clamp is messed up and give the chrome a clean so I can check condition.

Not sure yet on the headlamp brackets. The clamps on the ones I have are good...and I have some scrap 4mm ally plate (6061 I think) so might make my own. Depends if I can find an original headlamp assembly.

This afternoon's job is to make a bearing retainer tool ....

Nurse Julie:
Going great guns, well done. False economy and bad practice just hoping to do a top end rebuild. There are rubber seals and O rings that will be perished in the bottom end and it is a bit fool hardy not changing the primary chains whilst the engine is out. You could start it up after a top end overhaul and the bottom end could most probably be clanking away (more than they do at the best of times) and you would need to take engine out again.

SumpMagnet:
Good point and noted about the primary chain and tensioner. I'm more used to Hy-Vo types that last forever, and this is a roller one. Added to the list of things.

So it's strip down the top and both sides, flip it over and split the cases. Check gearbox bearings, shafts, gears, selectors. Check the state of the crank, replace the primary chain and tensioner, sort the camchain and tensioner/guides. Gearbox output bearing and seal will probably get swapped as well. Exhaust valve guides, find at least 3 more exhaust collets, add in a full gasket set....and replace anything worn out or broken. Which will probably include me by then :)

meanwhile....the shelving set aside for bits in the shed is filling up nicely...


All the smaller bits are labelled, fasteners replaced in situ, and boxed or bagged up


The frame and engine are in the back garden safely wrapped up while I tidy up and get ready for the next stage. I even had time to relax and experience the joys of the laid back easy rider bars this thing arrived with.....


you didn't think I was going to put  them on a bike!!!

While I try to figure out what might have been attached here....

Weld scar on the first layer of bracing....at the corner of the second. There is an identical one on the other side.

I also need to work out how to strip and paint the frame without losing the rivetted on ID plate. Sure, there is a seperate stamped number, but I would really like to retain it.
