Phwoar, however:
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.
