iv just got a 50cc moped second hand and it starts up only on electric. The kickstarter seems like it needs work. But the noise it makes is too loud. I dont want to buy another exhaust just yet but would it be ok if i set the idle on low, will that have any drawbacks as it seems to calm down quite a bit. Another question is that the front light, rear light (brake) and one indicitor light doesnt work. But the other lights do. Will a simple bulb change settle this ? thanks.
