hello my name is jason i'm new to the pocket bikes but not to racing. i have been porting and blueprinting motors for 15yrs. ihave raced on dirt and asfault. i have a cag as of right now with a chinese big bore kit 15mm flat slide, rocket key lightened fly wheel i did my self , modded stock pipe with longer stinger welded to it. just got done with motor yesterday ended up with a final squish of 29mm did some port work and now breaking it in wow. i have never done a motor this small as far as modding it but it's pretty impressive especially since i weigh 225. sorry for the long winded post but i just wanted to say hello and that i'll surely be doing more of these.
