I have a BNR 34 and I have bought the HKS Valve springs Step 2 with Jun's 264 IN/EX cams. Do anyone here can help me on the spec on measuring or calculating the shims? Does anyone have some information on this setup? I already tried to use the measurement that was provided by Jun, but when my engine starts, the cams are knocking :banghead: ...So, does anyone have any other calculations? HKS calculation? If anyone knows, please help me.

Thanks
