My girl rides a Liberty LS which has an electronic start, put an MLM pipe on it and get a good 45 mphs, not much out there as far as performance pipes but I did find an extra head and cylinder which I ported slightly. I have a Piercard cdi I need to throw on there but I don’t know if I need to retard or advance the stator. All the instructions are in Argentinian. I also put .35 reeds in in and a 40 tooth sprocket I had made for it. She like it but wants a top tank. I’m hoping to find a trac too tank and do an engine swap to keep the electric start which she likes.
