Ok I was riding today and looked down only to see my engine swaying left to right about 1"1/2 each way. The way I mounted the engine is the usual. Drill a small hole through the frame and use the mount that came with the kit. But I don't think that this is enough. My friend got a kit (66cc Grubbee Angel fire) that came with a thicker bolt. Mine came with a thin one that is very flimsy and I guess not doing the shop. Should I just go to Home Depot and buy a thicker bolt to use?
