The Yamaha Booster that was shown in the last video was insane😲🤩👌! I own a Booster too,it's named BWS here in Portugal, it has a W ported Polini 70cc alu cylinder fully tuned with all the remaining parts,is still being improved but it is far from being any close to this magnificent Booster with a LC cylinder on a vertical Minarelli block...Can you guys say which cylinder did you mount on it and what procedures did you do in order to mount an LC cylinder without having any further issues? Thank you👍.
