nobody will recomend cheap internal rotor ignitios... the artek or polini are the only ones that will ru the stock loom (well, the rest wire up but wont have a power feed to the rectifier, meanig fuck all lights unless you charge the battery manually) no such thing as a good cheap ignition, its ether good, or cheap. if you dont wanna spend up to 500 on one theres fuck all point replacing the original as unless you get a fully programable item it will be on par with a simple replacment cdi and lightend flywheel
