About lubrication, all oils have the following additives.

Detergents ( to dissolve sludge)

Dispersants ( to disperse oil to every nook and corner by wetting)

Viscosity indexer ( to keep the viscosity constant as far as possible keeping up with temperature)

Extreme Pressure Additive ( to cushion the impact of the power stroke acting on rods and journals, bearings and pins. They add Molybdenum Dysulphide, "Molyslip" is one oil like that some times add PTFE)

By the way Castrol name was due to Castor Oil which is an oil that dont attack rubber so used to prevent deterioration of rubber brake washers.

The oil if thin, will wet a surface and penetrate into corners, Best wetting oil what WD 40 ? OH NO NO NO, ITS SIMPLY SINGER SEWING MACHINE OIL, NEXT 3 IN ONE OIL.

A while ago I posted some pictures of my new bikes frame build, as you can see from the pics its developed a bit, in fact its been more or less finished for a bit, first test was Croft a couple of months ago, then Oulton, our final test was Donnington last month, and now its off to the Classic TT, as usual we made pretty much the whole thing, its been a hell of a lot of work, and its basically taken all our spare time for the last year and a bit by the three of us involved, hence the name SNT, Shaun, Neil Tony, but it has been great fun hopefully the weather will be good, and we manage to finish ok cant wait.

Has that BMW monstrosity got a matching ash tray fitted somewhere?

Just seen this bike advertised on a local forum

have a look at the rear brake actuating rod..

wouldn’t want to be relying on that in a panic stop

I hope it is nowhere near me. I will probably hear it coming, though. It will drown out all the local H-Ds.

[Jeff DaymanParticipant @jeffdayman43397]

Ah, the old Flex-O-Matic rear brake rod, and WFO pipes! Lovely. The pipes are an effective early warning system to nearby drivers as JA said. Revolting paint job. Oh the follies of youth….. and no ashtray in sight

Pound / dollar store oil in the crankcase to save money, likely….

As someone who built and MOT prepped a lot of bikes in my previous life, that rear brake would be a FAIL.

Ten of what?

A Manx Norton?
Or can you tell us what is particularly special about this one?

Pretty much all of a Manx can be bought, new, better than original, in 2019 too.

That's what I thought until I saw the petrol tank, but as far as I knew "Manxman" was the name used by Norton on a 650SS in the USA. However I found this

It is a Neville Evans Manxman – a google search will tell you all to save me a long screed but briefly :-

A Neville Evans Manxman 500, that he built in small quantities in the 1990s.
A cross between a manx (which he didn't have the rights to the name) and an Inter, as a short-stroke road bike version.

They sell for around the £20k mark

Thanx.

20k GBP does not sound expensive at all.

Andy Molnar engines are 10k plus alone. 2k for 4LS front hubs and brakeplates. Not looked at gearboxes and frames. I'm sure buying a new 2019 Inter/Manx would come to at least 20k.

That would be "Purple Poison" built by 2WheelsMiklos.

It looks like when it left their custom shop, it had a rather more direct linkage. There's lots of photos on the net if you Google This Search

Can't say it's to my taste though.

Stevie Wonder?

[Ian ParkinParticipant @ianparkin39383]

Yes he was quite rude when i pointed out his rear brake linkage wasnt much good.

This is whats wrong with not having to have a mot for over 40 year old vehicles

people change things with no real idea of the consequences of their actions

A friend of my brother sent this pic of two bikes seen in Mumbai:

[Clive FosterParticipant @clivefoster55965]

Looking at the original Purple Poison both brake rod and gear-lever connection rod are still bent. Less than the modified version but still enough to make control more than iffy.

Frankly I can't be doing with this sort of "look at the pretty (?) paint job ignore the crap engineering" thing. The perpetuators have worked quite hard to produce something pretty much unrideable over any distance.

Picking up on the Manxman pictures if you want rare with a Norton badge on the tank here is mine :-

Rotary engined Supreme Commander. 7 or 8 only I think. Started out as an ordinary Commander Krauser , around 100 of those about, then extensively, ahem, expensively modified with modern suspension et al by Richard Negus. Junking the Yamaha XJ900 running gear and brakes means that it stops if need be and has normal big bike handling not the standard "trail bike in super tourer disguise" version. Hafta say I rather liked the standard lively handling but it got the stopping problem sorted about a week after delivery with a set FJ1200 4 pot brakes up front. Had on before and figured out that mod pretty early. Now working on his second 100,000 miles "Grandad" (christened by my kid sister 'cos he is big, grey and sometimes smokes a bit) still has a more than adequate turn of speed when needed to put the explosion in paint factory leathered brigade in their place. Comfy behind the big fairing but speedo watching is essential as he thinks 90 mph is a nice relaxed cruising speed!

Anyway I like different, so long as it works well.

This Yamaha GTS shares garage space with the Norton. About 100 originally imported I think. My 65 th birthday present from me to me. Put 60,000 odd miles on one back in the day before an "I'm sorry I didn't see you incident" and liked it. So I gave into temptation. That one has less than 11,000 miles since new in 1994. Why spend all that money and not use it? The funny front end system works really well once you figure out that it its all done by counter steering. Lean (hard) on the bars and it goes where it should with militant indifference to road surfaces. Just don't forget the pathetic steering lock and excess weight. Fuel injected EXUP motor defenestrated to 100 bhp is the worst feature as its pretty gutless and needs too many revs for my taste.

Couldn't be more different to the flat torque curve and seemingly endless power delivery of the big rotary.

That joke rear brake rod brings back memories from the 60's, when I saw a 250 Royal Enfield with a non standard front brake. It had a torque arm from the brake plate to the mudguard bolts which faced backwards. To make matters worse, it had been drilled with lightening holes.
