Hi

Ive just been on the Yamada engines site and ive noticed that there is two versions of the YS 63: the FZ63 and the FZ63-S. Ive noticed the S is slightly lighter and in the picture it has a slightly different fuel inlet thing on the front. What is this bit?

Apart from that is there any obvious performace differences? Im planning on using one of theese on my Capiche 50 and i want the best performance possible
