    I was reading threw posts recently and saw some of you talking about 4 stroking and I was a bit lost until I rode yesterday and decided it must be the popping sound at the lower and mid RPM's. I am sad to say that I like that sound but do not want my engine running wrong, I have been putting a lot of miles on my bike the last few days and would like to know if I am causing harm to the motor and how to resolve the issue?

    I'd say that if you're 2-stroking at moderate cruising speeds (20mph or so) and also when going uphill, then I wouldn't do much about changing it. If you have good speed & power, then a bit rich is safer than a bit lean.

    If there is no 4 stroking you run the risk of seizing your engine, especially on a hot day. I rode mini bikes and go karts for years the best engines were McCullock and they 4 stroked and they were very fast.

    Thank you all for the information, I had no clue about it and thought the sound was normal, especially since my other bike is a 4 stroke.
