well, we have a magnetic sensor pickup which is represented by a blue and yellow wire in the manual. I found an MSD ignition for single cylinder engines that will accept magnetic pickup and it's pc programmable. This means i might be able to truly redline this zong, even though that might be a bad idea (knocking, worn rings, valve damage all possibilities of increasing rev limit). its a rather expensive piece for the bike and a super intensive upgrade, so i'll leave it for later, but i deffinately want to do it. If anyone else has made a similar mod, please share your results.
