Apologies but I wasn't able to get to the internet over the weekend. I double checked the manual, which is the OEM Kawi manual, and is the for the 2000 model with addendums for 2001 and 2002 and there is no range of pressures listed for the shock. They only list 142psi as the pressure. The instructions say that first pressure to 7psi and check for leaks and then pressurize to 142psi. Possibly the shocks are different between your model and mine.
