ok so i have a 2007 tomos lx a55 engine
First question i have is what is the carb that i have? is it the PHVA? and what mm? cause i am looking to do a little upgrade.
I just installed a brand new 65cc speed kit. i have a performance air filter, and a biturbo. Before i installed the kit i was doin around 40mph, now that i have installed the kit it seems that i am going a little slower. I have yet to upjet the carb, there is a 58 jet in currently. I know that i am supposed to up it to 74 or 76, but i want to know if the jet is what is keeping me from going as fast as i can.
also what size jet do i need? 6mm? again this is for the a55 engine.
all the info i could get from you guys would be great. Thank YOu
