Which Oil?

I gave the duke a service the other week but the clutch has started slipping, I'm guessing that it doesn't like synthetic oil?

I was just wondering what oil you guys recommend and how am I going to flush the old stuff out and will I have to replace filter again?

It was castrol 10w40 motorbike oil.
A guy at work has recommended Silkolene, never heard of it myself but he seems to swear by it.

I'm going to guess it may well just to coincidence that you changed the oil and now your clutch is slipping as that should be fine, Silkolene is decent stuff but like said I wouldn't have thought another oil change is going to help.

Is 10w40 the correct grade according to KTM?

The manual shows SAE 15w50 and SAE 10w40, I doubt it's going to be the clutch though as it's only done 10k.

Doesn't it state what type in your owners manual? Semi or fully synth

Checked the levels? It might slip if overfilled or underfilled

It doesn't say anything like that in the manual, I will check the level later.
