Hey Kommando, I bow to your (far) superior knowledge of lubricants! My expertise peaked as a teenager
- let’s not talk about that though!
Depends what its spec is, suggest you find out before purchase. Specs vary between markets so you need the local spec.
If it makes you feel better....I can't get it easily either! I have to order online. Works out about the same as other manufacturers so it's all good...I just need to plan ahead.Good enough for me Kev!
Not readilly available over here, so mail order for me. Thanks

Did I? I don't remember. Early bikes were labelled as Silkolene Comp 4 being recommended, but then Norton switched to Silkolene Super 4, the semi-synthetic equivalent. In 2019 Norton then switched to Motul 5100.......basically they offered a bigger sponsorship deal to Norton to be associated with the brand. I believe Norton today still use 5100.
So what do you recommend Stu?
Tiež mám predstavu, že na jar použijem 20W 50 alebo 10W 60. Motor bude určite menej hlučný. Len ma zaujíma, ako bude fungovať spojka.
"I also have an idea of using 20W 50 or 10W 60 in the spring. The engine will definitely be less noisy. I'm just wondering how the clutch will work"
Mal som skúsenosť s olejom v motokrosovej motorke, tiež to bol špeciálny motorkový olej a spojka nefungovala správne - šmýkala. Nechcem však spochybniť vaše znalosti. Bola to len hypotéza založená na mojich skúsenostiach.Aby som bol úprimný, ešte som nevidel špeciálny motocyklový olej, ktorý by nebol kompatibilný s mokrou spojkou... a keďže ma bavíme o motocykloch, necítil som potrebu ísť ďalej, ako je viskozita.
Špecifikácie stranou, pamätajte tiež, že to nepite
"I had an experience with the oil in a motocross bike, it was also a special motorcycle oil and the clutch didn't work properly - it would slip. I don't want to impugn your knowledge though. It was just a hypothesis based on my experience."
Definitely was on a thread here. Can't remember what one!
This is actually the best advice I have seen in a long time. This is the same reason HD and other OEMs initially put regular oil in their motors during the break-in period, and also, on the early air-cooled motors, they went with straight 50- and 60-weight oils. Air-cooled engines need all the help they can get. Look at the dirt bike market. Honda still recommends their GN4 for modern bikes, atvs and other machines which is a conventional oil from the 70's. They do spec semi and full for other products but a lot of air cooled not so much.
This happens with modern "chemistry" with full synthetics. They even claim it on the labels.
Sorry chap, honestly don't remember....and don't know why I would either. As I say, the very early bikes ran with Comp 4, the fully synthetic, but thereafter switched to Super 4, the semi synthetic...which is all I ever saw in use at the factory, until they switch to a new sponsor with Motul. The sponsor deals were basically all the oil, lubes and sprays was supplied to Norton for free, as long as we put the sticker on the tank recommending that brand. Motul offered the same deal, but also chucked in a larger cash incentive to have Motul on the TT bikes fairings too.
Nothing wrong with using it, it's just overkill for the engine spec.
Maybe me imagining it....not beyond the realms of possibility TBFSorry chap, honestly don't remember....and don't know why I would either.

Had a search, and according to the forum I've only used the word Comp once, and that was in this thread
?
