15w oil in front end

[Triggergee]

I'll watch out for that. Any recommendations on 15w fork oil brands and what's the difference between RSF SF and SAE?

[Disorderlypunk]

i used silkolene rsf15 simply because im not completly sold on motul stuff and the rsf15 was the next known brand for the right money from a big supplier
and as its from M&P the delivery is shit hot (dhl) and can be sure its not sat on the shelf for years

also just read this on a pyramid parts advert
RSF 7.5' is the new term for 'SAE 10'
[/size]how that works i dont know, but could lead to some confusion[size=large]

I went for Silkolene as it a name I knew and it is sold as Fork Oil its is apparently not the same as SAE 15 weight.
I started off with RSF15 and adjusted it by removal of a measured amount of RSF15 and replace it with the same amount of RSF30 until I was happy with the viscosity.
working it out the best I could I ended up with RSF 17-18 with the emulators set on 2.5 full turns in from initial spring contact (That is emulator spring not main fork spring)


If you do mix RSF do a longish run before you decide to adjust it some more, it took about 40 mile for the forks to settle down I think it is to do with the two viscositys' mixing or blending together.

15w in and Its made a world of diffrence in my opinion here's my reaction  https://youtu.be/egu9uA7nOIk

im loving the new oil - when my good camera gets back tomorrow i will show what the old oil had turned into
i have left it in a jar to let it settle and its some what unnerving - god knows how old it was

Ohhhhhhhhhh great thats  another thing I have got to do now then before I ride - Chain and sprockets soon, - including a swing arm strip and re lube (using a continuous chain ) I don't ride enough now as it is -- very tempted to by something new to cut out all the maintenance although I do get great satisfaction from doing my own maintenance it has to be said.

i have a scotoiler that came with the bike but i took it off instantly - they are easily forgot to be topped up
but what is an extra 10 mins to properly clean and lube your chain when you wash it (scotoilers dont clean)
my bikes are misused, mistreated and generally given a hard time but when it comes to maintenance they are looked after
forget buying a scotoiler and just buy a paddock stand as it far more usefull for everything


when you say you are using a continuous chain do you mean one that is riveted - i should hope so as split link chains shouldnt be used on bikes this size (the previous owner fitted one and it didnt end well for me but could have been worse if it flung the link 10 mins earlier)

With a Scottoiler my chain has been clean - and lubed. Practically never needed to clean it since the installation of the system. It does fling off, along with all the stuck dirt, and is continuously reapplied, of course.

No, he means it comes as a one piece endless chain.

I've been saying this is a simple and inexpensive improvement for years, why are you suddenly convinced now?  :lol

It most certainly felt a damn site better to me when i put the 15w oil in although like a lot of people including yourself i've no doubt that the old 10w oil that was previously in there was either so iffy and/or old that anything would've been an improvement, but as said, to me the handling is way better than before and gives a much more stable feel to the front end.  :thumbup

I'm with Slaninar, Scottoiler all the way. It includes a cleaning fluid and chains last 3+ times as long, that's proven. The container holds enough oil for at least 500 miles, so how can you forget to top it up? Would you forget to check tyre pressures? Better Scottoil than that sticky dirt magnet stuff that comes out of cans.

Yes I meant a continuous chain, thank you.
And its just that I don't listen to you that's all

Oh, okay, that's more understandable.  :thumbup

[size=1.35em]I found this table  https://transmoto.com.au/comparative-oil-weights-table/[/size]

[size=1.35em]it shows the viscosity of various fork oils.[/size]
[size=1.35em]you might be supprised at the viscosity of Silcolene rsf15 compared to Yamaha G15 which is Yamaha's 15W fork oil.[/size]

[size=1.35em]I was surprised at how the new ISO standard is being misinterpreted, see below...[/size]


[size=1.45em]Oil Conversion Chart[/size]

[size=1.45em]SAE-to-ISO[/size]



SAE                ISO/AW
10W                  32
15W or 20W        46
20W                    68
30W                  100

ISO and SAE are standardized specifications that define oil weight. This ensures that one brand's 30-weight oil is the same viscosity as another's.
This oil conversion chart is approximate.

[size=1.35em]I ended up going by the viscosity value and not what it says on the label.[/size][size=1.35em]the 15W  fork oil I ended up buying was the Rock Oil SVI 15 with a viscosity of 48 close to the Yamaha 15W of 47.3[/size]

Surprised?
Nearly just fell over!
Saturday mornings, eh?  :lol

[Disorderlypunk]

after leaving the oil to sit in a jar for nearly a week this happened
(this is just one fork the other is contaminated with leftover coffee granules)


[smg id=3112]
mostly water by the looks of that
