No matter what the parliamentary document says the MOT book says it must be as quiet as a machine with standard exhaust system in reasonable condition------another case where construction and use differ from MOT

Don't care what the government document says about noise. I have my M.O.T now.

That's an interesting read - the builders seem to have enjoyed the job. A couple of queries ....
1. Where is the oil filler? I'm guessing under the fuel filler flap.
2. Where will the number plate go?

It was only delivered late on Sunday and this damned thing called a day job has kept me busy for a couple of days, but tomorrow I'm taking the day off for as many miles as I can muster on it.

The Oil filler is in the top of the new oil reservoir , which is hidden under the tank. So petrol tank removal to get at it.

And the number plate is now fixed on a special bracket that was bolted to the bottom of the right rear suspension support, just not for these photo's

Gorgeous bike there. If you get a chance to post a video of her running, please do. I'm loving the exhaust by the way.

Yes, remiss of me not to have posted a video yes but I'll get round to it.
It's been running in very well so far, but having a oil drip from a couple of bolts underneath, one of the sump plug but what's this other one ??? On the left had side.

Is it the part called Cap, Oil Path (part 5 on the diagram)?

Its just a blanking plug, there's nothing above it. There should be an O ring, though.

Thanks Mr Davo,
 I was thinking there should be one too, like everywhere there's oil right ?

Whoops! Looking at this thread again I realised I put the wrong image in my last post.
Oh well, to err is human .... Try this one, it shows the part and the associated oil ring.

Have you got a leak from the sump as well, the pic shows oil gathering around what appears to be a crack but could be just a casting mark, forefront of the pic. It may just be oil running back from the sump plug but if that was the case why just around the crack?

Also, it appears your engine builders removed the blanking plug by hitting it with a chisel or something, common to do that when it's stuck in really tight and you don't want to chance rounding the head, they really should have replaced all the O-Rings as a matter of course, especially on such an old engine.
Don't play stupid with me, I'm better at it
