i got this bike cheap from sikpupy with an issues that it would sometimes be fine and other times it wouldnt rev past 5g. when pressing the brake the rpm would jump.

the bike was running on 1 cylinder which i think was due to rusty leads but now with that fixed its still got the first problem. i found a wire from the cdi that doesnt go anywhere and another one around near the battery. they both look like female connectors and the manual doesnt seem to have info on them. does anyone with the bike have a picture of the cdi or a wiring diagram of the cdi.
