S2R 800 which engine oil?

[Jontifosi]

Need to replace the engine oil any suggestions to help reduce emulsion?
I also note my bike has a glass view panel on both sides, is there a seperate reservior / oil for the gearbox?

[slob]

The window on the l/h side is for checking the timing, nothing to do with oil.
Use any good motorcycle synthetic or semi-synthetic oil that's designed for wet clutches.

[Jontifosi]

Thanks, probably try some shell ultima

[Zimbo]

Any good quality motorcycle oil, Shell will be fine, use the semi synthetic. Rock Oil, Motul etc will do just as well. 15W40 is what I always used.

I always use Shell, never had an issue with either wet or dry clutch motors

[Jontifosi]

Just a hassle trying to find somewhere i can go buy some. Even tried the looal Shell garage and all they have is 1ltr bottles. Halfords are castrol only.

[slob]

Stay away from petrol stations and Halfrauds, you'll end up with a 'car oil' that's not suitable for a wet clutch. Try your nearest motorcycle shop

I got some from ebay and it came with a new oil filter as well. I think I got Castrol power 1

[Jontifosi]

I bought the Shell ultra plus a K&N filter from M&P (ebay), £38.
I have the oil rad so thinking - Should i leave the rad in palce for drain down then put it lower than the sump on the refill? or isn't this necessary, does it purge itself?

[slob]

You don't need to (re)move the oil cooler during changes.
The take off/return is at the filter housing, it'll drain down.

[utopia]

Since both the flow and the return connect to the top of the oil cooler, I would assume that although the lines themselves will drain, the cooler will not.
In fact, Capo is always telling me that I should unbolt the cooler to drain it properly at oil changes, otherwise the new oil will be contaminated with the residue of old oil left in the cooler.
And I probably should, but up to now I've never bothered.
I usually use the excuse that the oil is being changed before its strictly due, so the residual oil may be "used" but its not exactly "old" just yet.

[slob]

Good point, even though it's a very small percentage of the overall quantity, there's always going to be some residual contamination.

I always empty the cooler when doing an oil change.

And the (non-standard) cooler on my Monster holds around 1/2 litre...
