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
...So, does anyone have any other calculations? HKS calculation? If anyone knows, please help me.
Thanks
