looks good, apart from the radiator. can you get one that sits between the front rails, like some the cruiser ones do?

Hello all, thank you for the kind words.
Next, the bike will have the MSVA and get registered, and I will ride it for whatever time I can before winter. Then it will be completely disassembled, cleaned, painted, and rebuilt. The following items will be revised:
  • New blinkers. Although I like the integrated brake lights, the blinkers currently installed look cheap, and way too big. They will be replaced.
  • New headlight and shell. This part was also too cheap and looks bad.
  • New mirrors. Possibly just traditional round chrome ones.
  • Some kind of dash cover, so the backside of the speedo doesn't look so unfinished. I could have a backshell of some kind 3d printed maybe.
  • Rear brake pivot will be revised. The actuating arm is too long and the pedal needs a lot of pressure.
Brad I am thinking about a different radiator, but will have to have one made. I haven't been able to find one that is the right shape and has the outlets in the right place.

So i thoroughly read the MSVA handbook and there is a deman in there that the fuel cap cannot be higher than 15mm, the GT550 cap is more like 25 to 30mm. So I was thinking about doing this anyway, so why not! I got a Harley fuel cap and bung and had a go. First I cut out the stock cap bung, and folded the resulting tube down so the new bung could sit on it.
I drained the fuel and filled the whole thing up with water. It is a little bit of a pain, but I cut, grinded, and welded it with no explosions, so it definitely worked.

That might have worked, but I ended up using the top of the original bung which happened to fit the tank and the new bung nicely. Tig braze tacked that in, then went all the way around. It looks ok. It still is higher than 15mm, but I can temporarily install a flush-mount cap from the HD aftermarket, then use the cap I like after the MSVA.
Oh, and of course it leaks. I will have to re-braze it and pressure test a few more times.

I had to rent a van to bring it to the MSVA inspection. All passed, no problems. There are a few tricks to the inspection that I was lucky enough to identify beforehand, and it paid off. The examiner said that a lot of bikes fail first time because the fuel cap is higher than 15mm, so all that work I did to make it flush was well spent. Also you need the pilot light in the headlamp, evidently there are a lot of failures there too. Ad finally, note the clear plastic number plate that I put on there temporarily, just to hold the red rear reflector. Need to have that.
All in all a great experience, the examiner was very helpful and professional, and used fair judgement. I have also insured it on the VIN only. Now I fill out the V55/5, and will get a V5c.
If anyone has any questions about this process just ask. I learned a lot while investigating it.
In the 4th picture the LR indicator is wonky because I hit it with my foot while swinging a leg over, this has since been fixed.

I ordered some LED spots for the kitchen, but they ended up being the wrong size. So I bought a cheap transformer and mounted them on a piece of wood for some extra lighting in the garage. Very effective, and they run cool. Ugly, but only cost around £30 total.

well done. i don't do roadworthy certificates any more, but i did when i worked at a dealership, and the amount of people who would come in and argue over absolute shit because they'd done no prep used to shit me up the wall.
