Worn cams: worth regrinding to Stage 1 for my setup?

11 Sep 2025 14:50

Hello, I have a spare cylinder head that I plan to rebuild, and also a set of worn camshafts. Would it be a good idea to send the cams out to be modified into a Stage 1 profile?My current setup is a stock head, Mikuni RS34 carbs and a Delkevic 4-into-1 exhaust. With this configuration the engine pulls very strong up to 8,500 rpm.If I rebuild the spare head with larger valves and use the modified Stage 1 cams, how much improvement could I expect?Does anyone have the exact Stage 1 cam dimensions that I could use to modify the cams here in my country?Any suggestions are greatly appreciated. Thanks!
