I'm looking for a bit of guidance in which way to turn next with my engine . I have a classic rapido 225 gp200 gearing 19/46 sprockets jl3 varitronic ignition 28 mm phbh at the moment and it has been faultless if I'm honest . But now in need of a bit more top end speed and was wondering if anyone had any views on the above kits pros/cons .will the internals be ok to use .Or should I just stick with what I have and be satisfied

Regards j
