Just tweaking the toe-in and lean out. Whenever I adjust one thing everything else moves, so it's backwards and forwards with the planks and big setsquare. So I've stopped now for the day. A nice cup of cocoa and a Borders ginger and chocolate biscuit (highly recommended) await. When I've made them of course.....

All this tweaking Ian - has your dodgy knee allowed you to ride it yet?

Not yet, but improved a lot over the last week or so. I was starting to think it was permanent. The temptation is always to do too much too soon. Back in the shed in an hour or so to continue the tweaking......

They might be but are from a bakery in the Borders. Fortunately Waitrose stock them!

These are they:

Triumph all finished and ready for the MOT test Thursday. Depressingly I can’t ride it! The right knee will not bend enough to get my foot on the footrest even though I’ve got 120 degrees of movement now. I can get my foot on the rest of the Intruder (just). So it’ll be MOT and straight up for sale if / when it passes.

Looks a treat fella, looks a treat.
Pity you can't enjoy it for a while.

Tha Triumph looks great Glyn, well done.

That's the same knee problem I had after my knee op (and still have to some extent 14 years later). I've had to mod various bikes' footrest and seat arrangements to cater for this. The B'Zuki had footrests about 6" further forward than standard, fitted by the bloke who built it. I assume for the same reasons, but it does give a very relaxed riding position.

Re MoTs: I'm still in a quandary as to whether the replacement engine counts as a "significant modification" making it ineligible for MoT-free life. Rather daft as the engine isn't examined in the test other than for exhaust noise. I will take it for one later in the year just for peace of mind but will probably revert to ticking the box in future. Interestingly, I've got a sensible insurance quote from the broker that refused me after my theft 2 years ago and they are perfectly happy with the engine change. And have documented that.

How will you get the bike to the MOT station Glyn if you can't ride it? I'm guessing you'll have a trailer or perhaps get a pal to take it? Yeah, that looks mint.

I’ve arranged help from a friend with a van to travel to the testing station.

Ref the changed engine Ian. Who will know? Locally theres a fella driving around in a Morris Minor Traveller who openly boasts about paying no tax or MOT as it’s number plate is over 40 years old. Under the immaculate body, there is the chassis, axles, engine gearbox etc of a Mazda MX5. He doesn’t get it MOT’d so who knows? Next month my TZR becomes 40 and so I will report back what steps I will go through for it to become historic.

Re changed engines - or indeed a modern car with classic bodywork - it's not a problem until it's a problem. What happens if your local Morris Minor MX5 owner has an accident? That's when questions get asked, that's when insurance companies look for an "out", that's when PC Plod starts pondering if there's a case to be answered.

Glyn's mate's car would definitely count as substantially modified so would fall foul of the rules, vague though they are. I have explained to my insurance company exactly what engine I have fitted and it's shown on the insurance schedule so I think I'm OK with that. Although we'll see.

Re the TZR: it's not 40 on its exact birthday but as I remember the start of the calendar year following that. And it's date of construction not first registration just to add confusion (although there are some weasel wordfs in the link). And to add more the wording for MoT says "built or registered" and seems to relate to the actual date of construction / registration not the 1st January. See link below.

There's a lot of discussion in sidecar circles about whether the leading link type forks lots have fitted are substantial modifications. I actually think they're more so than my engine change but what do I know?

Currently struggling with my air compressor which loses all its pressure when it reaches its target pressure. I got a cheap regulator box for a tenner from ebay but that hasn't saorted it out. Always something.....

I've fixed the compressor thanks to Anthropic's Claude. This is the conversation - if anyone's interested. I must say AI can be a great help.

Excellent Ian although I believe the model used in their office vending machine became a bit like Hal when threatened with removal...

I had not read that bit about the year after for historic vehicles. As my TZr is imported I had to have a dating certificate which I do hold that states the bike was BUILT on 1st May 1986. So it might seem that I will have to wait until 1st April 2027 to obtain the exemption. It will be a few weeks off 41 years old by then.

An interesting car modification story here, strange when there are tv programmes documenting major patch repairs to rotted A and B posts

I forgot to add that the Morris Minor / Mazda MX5 is fully insured by Adrian Flux in their full knowledge that it is a 2 Litre Mazda with 6 gears. Apart from bodywork it is an unmodified MX5 with many of the safety features intact. Given the modern brakes, steering and suspension mechanisms it is probably a lot safer than a period Morris Minor. So, in the event of an accident Mr Plod might not be overly concerned. It’s the revenue that could be missing out here together with the loss of the MOT fees. Grey area for sure. I understand that the government feels that a 40 year old vehicle generally belongs to an enthusiast but I am seeing more tatty old VW golf’s, full of rust, still on the road and I would feel happier if the MOT test was a requirement for all. I could understand “less stringent “ for vehicles with rod brakes and leather shock absorbers but they should still be covered by some sort of test in my mind.
