So there seems to be some debate on what size valves can be fitted in these SOHC heads. I have a 1500 euro version with 36mm intake and 33mm exhaust and some say that 37.5 are the largest intakes that can be installed on this head? Another member just showed me a picture of a SOHC with 40mm intake and 35mm exhaust. I guess I'm just asking what my options are if I want to increase the intakes only?
