Would I notice a big difference in power?
Going from a ALL stock GY6 150, clutch and all. To---
-GY6 150
-Stock cylinder size
-Large valve ported and polished head
-A12 cam
-Ported intake
-Polished carb intake
-Jetted carb
-UNI filter
-Performance exhaust
-10g sliders
-Yellow clutch spring
-Dr. Pulley clutch kit
I was thinking of going with a 61mm big bore, but not sure if I want to spend the extra $$.
