Broken cam chain

You could also go for the 650 engine I believe it don’t take much to for them.

Personally I would drop another lump in there, but, that depends on availability, when I last was in the buying market a motor with good compression and free turning was £150  plus delivery, tested was double that. Given the cost of a gasket and seal set and any parts it was a no brainer, and because delivery was quite a big lump of cash and the bikes worked hard I just bought  an engine or 2 if I had  an issue.

Hi All

Thanks for all the suggestions.

I have been stripping down and cleaning up parts over this weekend, getting the Rocker cover, head and block ready to go to a local engineering firm for the once over and to get an estimate on the work required.

I still have yet to crack the crankcase open and see what awaits me inside. I am pretty sure the bottom cam chain sprocket will be in a similar state to the top one, so in order to get ahead of the game: does anyone out there know of any good condition Crankshafts available for a 1976 550f1, I have found a new one but the price is very scary!!!!!

I have been trying to add some photo's for those who are interested, but so far I cannot get the post to send with pics? any suggestions? I live on a boat and only have interweb via a mobile phone hotspot. Maybe this could be the problem?

Bryanj. Still interested in that cam sprocket, as and when you may find it.

Richie, maybe not the best way to do it but I post the photo to myself on messenger. You can then save the image received in the message to your album. This method reduces the size to enable it to be posted as an attachment to your post on the forum.
There maybe a better way to reduce its size but that's always works for me.
Make sure when you post the photo to yourself you are in a wifi spot otherwise you may get charged.

Thanks Laverda

That all sounds a bit long winded for this technophobe! Not even sure I have messenger.

Thanks for the suggestion though. I checked the file sizes and they were well within the plaited KB stated on the site?

I'll give it a go and see what happens!

Hah!
Don't know how Spell Check changed Allotted to Plaited!

You need 5 posts to start adding pictures Rich (which you now have )

This stops the most blatant spammers.

Ah!

Thanks for that info Steve. Sensible!

You may all regret me passing the initiation proc as though!

Hi all

I am pleased to report that the top end has returned from the engineering firm with a full bill of health. They have honed the bores, skimmed the head, seated the valves and checked the valve guides.

Now I cannot put of the inevitable bottom end rebuild! The part of this saga that worries me the most. Gonna need to free up a little time for this part. Don't want to go away and come back to it with no idea where all those bits go and in what order. Here's hoping the bottom cam sprocket is ok🤞

Will post some pics over the weekend. It all looks shiny and new😁
