Well you could contact us at toys4boys here in Calgary AB Canada we have a few things you could add to it. I recommend the 25mm carb and a high performance cdi it's a sweet combination. My mini hummer ( 110cc ) has this combo on it and we had it up to 75 km an hour with a 200 pound guy on it.Yeee Haww! Maybe a sprocket change depending on what you want out of it. You can contact us at
