    Hey this is my first post on motored bikes but i just got a 70cc motorized bike today for christmas so it was the first time it had been ridden. I was following the break in procedures and only riding for 30 minutes at a time and taking breaks in between. Whenever i would go back outside i noticed when i would just start it and start riding it would be lot faster and more responsive. Just wondering if this has happened to anyone else or is just because the engine is not broken in yet.
    Thanks, Zac.

    Its probably a mixture setting due to your current carb settings or possible air leak.

    A cold engine requires a richer mixture setting and when it warms up it performs better with a leaner setting. The fact that your engine runs worse when warms up makes me believe the aforementioned is your issue.

    It could be many things......I suggest searching and reading. That and posting the question under the 2 stroke forum after making your introduction post might get better answers.
