Yes it is, don't ask how I now....
I also rivet the chains, as I'm used to do it on the 450's too (endless isn't possible)

Great to hear from you. Do you just use a regular rivet tool or have you developed any special technique or tools?
Access on the 450 must be very difficult.

That looks beautiful, & its definitely going to be as good as new once finished, no actually better than new!!
My chain-riveter wouldn't get down to the chain, so I got the engine near to a workshop upright girder, turned a small chain- pin recess into a 12" length of round bar-stock, carefully positioned it all on wood & rags so as to 'take up the slack', turned up a rivet-snap from more bar-stock, then gave it a good whack!!
Its amazing the make-do emergency 'bodges' we used to do on the rigs & heavy plant maintenance!!
It'll probably self-destruct itself now!

Regular rivet tool and patience, just doing it step by step. The difference between a good rivet and a cracked one is small. I think the CB72/77 and CB450 rivet room is more or less the same. The extra issue with the 450 is that the chain is under tension of some valve springs, and just doesn't want to stay in position.......
After some serious riveting I have an appetite for mushrooms :)

Yes - I remember the days when we used to strip a bike down over the weekend and have it ready to ride to work on the Monday morning.
My agricultural upbringing also taught me how to get things running with the minimum of tools.
Nowadays it's all a bit more relaxed ...
I tried to 'do it right' with the riveter but I think I'd be more comfortable with a lump of steel and a punch.
