I bought the rc2dh damper and dual flow rebound to go into my lyrik CSU. On the Rock Shox website it states at 160mm travel that you need 187ml of 5wt oil in the damper. Followed this diligently and the forks felt awful, harsh, ramping up, the rebound and compression did virtually nothing at either extreme.
I contacted the SRAM tech centre on Sunday night and didn't really expect a response as i am a member of the public!! But yesterday ane mail arrived explaining the best way to fill the fork was using the oil height method. The oil should be 115mm down from the top of the threads according to them. So off i went to the shed last night emptied the oil, refilled up to 115mm from the top. Whacked the damper back in and bingo! They feel ace now! probably 30-40ml less oil than on the oil chart.
