All I need is a high performance cdi and some porting on my 48 cc but not sure if it'll work with just the boost bottle and I'm not sure if the Reed vales will fit this engine cause I had to modify the expansion chamber and the intake manifold to cause the one that came with the boost bottle was to small. As far has how fast I wanna go . I wanna go 45 but be able to cruise at 35 mph, as I have my setup now my bike. Nearly hits 30 and if its a good day I'll go 35. Also I'm still fighting with the issue of it for stroking at top end , and when I adjust the carb needle it'll run super lean. The 4 stroking is only moderate in term of it only happens here and there at top end
