Hoca 169-405 47mm Kit. Partsforscooters has them for $150. Really easy direct fit kit that works great. To get the best results though you will need a different exhaust than stock and change the reeds. You can get Boyesen reeds listed for the Kymco 2t, but I found that the reeds for a Kawasaki KX65 from '00-'07 work wonders. I have 2 2013's, mine and my sons and I have a Cobra Racer exhaust on his with the kit and mine has the reeds done with a 100 jet and a Leo Vince TT exhaust. Mine has a better top speed but his has better pull through from the start through top end. Changing his reeds to the KX reeds tomorrow with a true 19mm carb. May have to break down and get a TT from SIP Scooters because no one else has been able to get me one in.
