Hi, I have been looking into tuning my 1997 Piaggio Typhoon 50cc. Since looking into the bike and viewing various pages about them on the internet, i have notices that some alterations where made to their production in 1998 i believe. I was wondering if anyone could tell me what these alterations where. I have wrang several piaggio dealers to try and find this information out but none of them seem to know. I would also like to know what size carb my Typhoon comes with as standard. Anyone who can shed some light on my situation i would much appreciate it. Sorry if this is in the wrong thread but i have never posted a topic on here before. Cheers, Chris.
