I have tested many options and bbks for the 50cc scoots and have found that the best option is to run a stock combustion chamber big valve ported head you can't buy this anywhere on the net only ones with the combustion chamber cut to 50mm but I have a connection to have these made pm me if you have an airsal and want a stock chambered big valve ported head
