Actually I think you'll find it's the AE35 Antenna Control Unit that is the most unreliable part on ANY starship.Mr. Dazzle wrote: ↑Thu Aug 19, 2021 10:54 amThe core ejection system is the least reliable thing on the whole ship isn't it? Why can't they make it work as well as the lights and gravity? Those never fail.KungFooBob wrote: ↑Thu Aug 19, 2021 10:49 am Have you tried re-routing power through the main deflector?

Re: Classic Triumph Bonneville
Is there a local branch of the Vintage Motorcycle Club or similar?
You might benefit from some old fart seeing it.

Re: Classic Triumph Bonneville
Guy picked it up today. He was spannering for BSB this weekend so he couldn't get here any earlier.
He tried it and then announced "there's something fundamentally not right there". Took the plugs out, kicked it over a few times with the clutch pulled etc. and sucked his teeth a bit. "Gonna need to get it back to the workshop and have a look".
So yeah, not just being a fanny

What's the betting the crank is in backwards or something similarly obvious, but not.Mr. Dazzle wrote: ↑Tue Aug 24, 2021 4:13 pm Guy picked it up today. He was spannering for BSB this weekend so he couldn't get here any earlier.

In fact - who wants to take odds on any of these:
- Reversed Crank
Cam timing out by over 90 degrees
Conrod not straight
Wrong Rings
Wrong Pistons
Wrong Valves
.....

Re: Classic Triumph Bonneville
Bottom end hasn't been apart, so that's a few off
I'm betting either gearbox is bent somehow, or the head is. When the head was off it turned over a peice of piss, whereas now it doesn't. I don't think it is and I checked all the gaps carefully....but it doesn't turn over now and it did before.
The fact you can turn it over quite easily via the crank pokes a hole in that theory.

I saw W.C Fields in a film, helping a stranger with a broken down car, by suggesting: “Is it the wheelbase?”

Re: Classic Triumph Bonneville
I'm inclined to agree....the other option is to take it all apart and put it back together again. But I don't know what (ir anything) I did wrong the first time

Re: Classic Triumph Bonneville
Have we already (through rational deduction, Watson) eliminated lumpy 11:1 pistons contacting the head or the valves?

Re: Classic Triumph Bonneville
I think that was eliminated by turning it over at the crank.

Re: Classic Triumph Bonneville
Yeah, unless the valves are bent now and that's why its hard to turn!
It has compression and seems to turn around smoothly enough via "alternative methods".
Thinking back, I reckon the problem first cropped up when I torqued the head down. Prior to that it was dead easy to turn over, afterwards it became more difficult. I had the bolts just past finger tight while putting the pushrods in, then I torqued them down tight. Everything moves maybe ~0.5mm at that point. But 0.05mm is enough to make things stick if it's in the wrong place.
At the time I assumed it was cause you're now properly moving the valve springs, the rockers have load on them (from said springs) and the pistons are actually sealing fully. Maybe not though.
I can't see what torquing the head would do, unless something was binding as Iccy says. Only the rockers could do that though think....which is why I said maybe the shafts are bent. But they're brand new...
Other option is that the head itself is now bent. But I measured the gaps/PRT crush carefully. I've also now got what are essentially undersized seals in the PRT tubes, so if anything I'd expect leaky PRTs not a bent head.
I also don't think its anything to do with me taking the primary drive apart. The problem was there before I started poking around in the primary, AFAICT.
