Sorry if its duplicated. Chain advise

[Guest Mac750]

I have the OE chain fitted and the bike is on 3,800 miles. Not had to adjust it yet at all, but it has had EP80 gear oil from a loobman oiler during rides and after each ride when is warmed up I "paint it " with a brush and EP 80.  Funnily not much fling but the back wheel gets grubby but cleans off quickly with WD 40. Non on the rear tyre. But some drips on the garage floor over night which is caught by a strip of thin ply wood, checked the links and non seized as yet.

 OE chain on 3400 Miles.  No adjustment yet

Cleaned first then oiled with a brush every week or additional oil if needed during the week.

Still looks as good as new
