A bit of progress over the last 2 weeks.
Got the engine running and idling smoothly. I tried to take a video but my phone battery died before it saved! I had done the bench sync incorrectly but after re-reading the process I got it in the end. Put some vacuum gauges on them and they were pretty close.

Removed electrics - all going in the bin.
Removed the shocks and triple tree - the fork tubes are in bad condition. I'll either need to re-chrome them or source replacements.
Removed the rear wheel - one of the wheel spacers was missing and had been replaced with..... 3 Nuts!
and finally got the engine out. I layed the frame on its side and got it out that way. Was hard work by myself but I got there in the end.

The engine cosmetically is pretty bad. I'd like to re-paint it but I've read in many forums its not good to paint an assembled engine (shouldn't paint over gaskets and bolts and you can never get it fully clean).
I emailed a couple of blasting companies but they all said they wouldn't touch an assembled engine.

Leaves me with a couple of options.. Do a top end rebuild and get the head, barrels and cover blasted in the process - then do my best to clean and repaint the case assembled

Or completely strip the engine and get it done properly.

I think I'm going to do a top end anyway, I don't know the bikes mileage and I want to check the tensioner, rings and valves/guides.

Thoughts?

On a separate note, I'm not putting this bike back to stock so will be selling/passing on a few things. Any interest in the below? If there is I'll take some photos.

Exhaust headers (550F 4-1) - they would need re-chroming and are rusted onto the collecter. I could cut it off and check the condition of it if there is any interest. I think they're just a bit rusty and don't have any dents.
Controls left and right
Seat and pan
Grab rail
Headlight ears

Sure Trigger, it will be a little while as my mate is away now and I don't have access to the garage.

Here you go Trigger. Not in the best condition. No dents or holes but a few deeper grazes here and there.

I also have a Tank in terrible condition. No idea why anyone might want it but you never know.
