Sorry I confused you No I don't have a boost bottle on my bike but from what I've seen they appear to have an effect I could be wrong. My bike is a 24" Huffy mountain bike I had for years. I have had my motor mounted for about 2 months now and I love this thing I am looking for "Hop ups" or Mods to improve the performance. I have nowhere near the amount knowledge of these motobikes many others have here but with the gear being my first I just thought I could shed some light. Sorry if I gave the wrong impression.
