Title: It's all about CC's
Post by: 118118 on August 13, 2017, 10:51:17 AM

HI,
I'm new to Kymco scooter after having various Italian jobs, 2 stokes and big bikes.
I have an Agility RS 125 in the UK. I'm looking at increasing the bore size to a 150cc or above. Am I correct in thinking that these bikes (and GY6 engines) in the US are standard at 150cc? If so, what are the size of the main & pilot jets in the carburetor? - currently 104 & 35 here.
If I go above 150cc do i need to up size the carb, air box and exhaust? Is there much power/torque increase?

Any advise would be very helpful.
Thanks.
