Hi. I'm looking at buying a 2014 Typhoon 125 4t. If I buy it I will be wanting to put a big bore kit on it. Seen the Polini 198 big bore kit on ped parts. Thats what I'd like to fit to get more power and speed, acceleration in particular for pulling away at lights etc. Has anyone ever fitted or seen anything like this done, or the results? How much improvement am I likely to get and is here any problems I might encounter? An advice would be great. Thanks in Advance.
