i have tried this on a few different 50cc kits and it works well.apart from the performance boost it reduces vibration and engine noise the only downside is there is less surface area for cooling but i havnt had any problems

first i remove the bottom fin so the top piece can push down on the dome and gasket hard and elongate the holes to fit the 50cc stud spacing


then fit the copper gasket and dome



then the top piece



on my friends 50 we had to use 2 gaskets as the compression was too high and it was pinging
