Hello, i have run into a problem with my powervalve cdi unit. the unit that controlls the wires that controll the powervalve. The thing is that, it worked before i started to trying to fix it, but i wasnt working propperly. i wonder do they still make this type of stuff? or a replacement part. Anyways at the first it when i turn on the ignition, the cdi unit tryed to do a clear circle but it just lagged front and back and stopped. I tryed to touching the cabels and the cdi started to go mad. and i cut som of the cable and fitted on new connectors, and it stopped working. maybe all the cables are rusted inside and need a replacement? is it possible to weld new ones on? i checked the whole bike for errors and i got electrical power from the (brain)cdi, and to the cdi unit but its very low. Round 8v. On each cable. What can i do to fix this issue, or the best way to make the bike run as good as it gets
