Review on 🛵 GOOFIT 44mm Big Bore 53cc 54cc Top End Kit for 47cc 49cc 2 Stroke Engine Mini Quad Pocket Bike by Ryan Bennett

At first glance this kit appears to be of very good quality. But after final assembly of my motor I encountered 2 problems. The first item in photos 1 and 3 is the top 2 cooling fins, they do not match the head and cylinder fins. Figure 4 shows what the alignment should look like. The second and main problem is that when the piston is down it is not aligned with the bottom of the exhaust. The piston is blocking about 20% of the exhaust port and there is no way to fix this.
