Phwoar, however:
I'm extremely reluctant to let go of it but I'm pretty much only riding on dirt these days and I don't want it just gathering dust, it needs to be ridden and loved.
Which seems to be the fashion!!
As for shorter insurance periods, it’s not worth it. I asked about a shorter term insurance to get the second bike insured until the first needed renewal, but it worked out more expensive than any other variation (adding on late, entire new policy, etc).

Talking of dirt, update on the Sherco. I have had a lot of trouble the past month with it, it bogged and refused to start from cold. After cleaning the plug and carb, it would work for a few hours then bog and refuse to start.
It was something like: seems okay for the first half-hour of practice, second half-hour it gets boggy. Across a week of three or four practices, by the end of the week I wouldn’t like the starting sound. It would take more than two kicks, and overall just sounded and felt wrong.
Two trips to the shop for advice, including a new spark plug and such. The main takeaway was, “the plugs are rarely a nice brown, they’ll be a bit black” and “you really should clean the carb before/after each trial, so if you’re getting three hours practice in a week, that’s more engine hours than a typical trial”.
Okay, okay. 2-smokers need constant babying with a clean plug and jet-cleaning, but after the third week of pulling a black sooty plug out, I was sure it was a rich fuelling issue over anything else. I want a chocolate spark plug, no matter what they say.
So, the correct thing to do is change one variable at a time, by a measured amount, and then check results.
Instead, I turned the fuel/air screw out 1/8 turn, and moved the incredibly rich main jet clip up one notch. Plus, I reduced the oil in the fuel very slightly.
Two one-hour practices, and the bike would start on the first or second kick, idle more comfortably, woke up as far as power delivery, and doesn’t seem to bog over time.
Phew. Getting closer to reliable running.

Seems ironic doesn't it, although kind of reinforces why (personally) fast bikes are so much better than cars. Shouldn't complain when thinking about the equivalent tax/insurance cost for a car that can give a similar buzz.

Does reducing the oil effectively make the mixture richer in that there is a higher proportion of petrol in the fuel / oil mix? If this is the case you might be doing several things at once which will counter each other?
I don't know about modern 2 strokes, but the older bikes I play with use pre-mix and there's always a range of opinions on this - certainly there are machines on club runs that often suffer from overheating, generally attributed to running too lean, and then you hear things like "it's supposed to be 24:1 but I put a bit extra (oil) in to be sure"...

I think the solution is through that screw. You can also try, if you find a way, to give more air from the intake, maybe just temporarily only to test it.

Nicely done!
Saw this on eBay and it's right up my street.
