ok so i bought a K&N oil filter (KN 204) which was labeled as equivalent to the stock rocket one.
however on me spare engine that landed from the US it had a KN 191 on it.
I looked them up and the 191 is 1mm longer and 4mm wider in diameter.
Fitted the 204 yesterday and it's fine. It's the same dimensions as the triumph one that came off it.

So i'm just wondering, what filters do you guys use (if K&N)?
