Hi all
Was thinking of getting a head with bigger valves in my current 06 SuMo race bike. The easiset way seems to get an older head but I'm not sure what years had what sizes....
The spare parts manual says that 04 and onwards has 35mm inlet and 30mm out.
After searching this excellent site I found out that the 03 had 37mm in but nothing about the out size. Does anyone know??
Does 01 & 02 have the same size as 03??
Is it alright for me to order the older stock valves and make them fit my 06 head or should I look for another make of valves? Titanium sounds great but way too expensive...
