So I got a 2006 Kymco Agility 50cc 4 stroke. I'd like it to have more zip and was wondering about performance parts. Does anyone know if parts from the Super 9 would work and if they'd improve anything? Is it worthwhile to get a performance cdi or air filter? Are ebay 70cc kits any good? How heavy of variators would be good? I would like to do these mods myself, so is there a good place with pics/walk throughs? If not, I'll probably buy a Haynes scooter manual.
