Piston rings wornout at 5k miles, put in a 80cc bbk and a 90main jet, now its roaring.
The previous owner glued the cdi harness onto the cdi, i can't get it off to put on a racing cdi :(

Anyone know where i can get just the cdi harness and not the whole thing ?

Scrappy's sells the cdi harness but don't know if you have found a work around by now but here's the link : http://www.scrappydogscooters.com/COMMON_PARTS.html
