“I’ve never touched a scooter engine before but the swap was pretty easy to do it took about two hrs and the only thing I had to install separately was a carb I also bought from them,before the swap I would top out at 28 mph but after the swap I got it upto 53 mph and that’s off a gps Speedo app,I went all the way and went with the 44 mm stroker crank,,I’ve since bought a 600cc Silverwing but my little scooter ain’t going nowhere,it’s part of my stable.”
