I have a gs moon 150cc buggy. It uses a dc fired cdi, i was wandering if the a performance cdi and h.o. coil would help the overall performance. Here is a list of what I've done so far. Opened up the exhaust to around 1.5 inch, I'm running a spectre pod filter with 3 inch outlet, koso clutch and variator with the stock main spring and 10 gram rollers.
