Question: What cam shaft can i get for my engine and what is good etc? How much?

Engine: Ducar 125cc 54x54
Carb: Will be getting the oko treatment. (Not 100% but most likley)
Head: Stock head will be getting ported
Valve springs: Will be go for some new HD ones.

Why?
I want to get a bit more out of my engine.

yer, a bigger cam just rly moves the rev ranger higher so leting the motor rev higher pulls more power,

make sure u get a good port job and cam and should be good

from my experience a decent cam improves the power through the whole rev range, not just the top end, especially if you do a bit of porting as well.
