Ok so I set the rear to 33% of available travel with me sat on the bike went out for a ride and felt great..... however the front is hard as hell and i'm struggling to reduce the sag, even with the preload backed right off i'm only getting 55mm of sag on the forks with me on the bike.

The front springs are Ohlins code 08716-60 (36.5/590/6.0)
I also got with it Ohlins fork oil which is code 01313-02 with viscosity of 23 cST at 40 degrees C

Installed using the original spacer and 145mm air gap as per the manual, so don't know what's a miss here, could it be the oil?

I thought this would be straight forward...
