Nearly finished with my first kit, an 80cc one that has a rather low quality feel to everything, so I'm worried about the lifespan of it. I was hoping to communte to work for 5 months of nice weather. 20 miles one way, 200 miles a week. Can this really last for almost 5000 miles? Assuming synthetic oil at proper ratio (16:1 break-in, 20:1 afterwards). Is there something typical that goes out first, second, etc?
