Re: OK very overwhelming, quick question ....
All of your concerns are valid, but if you ask me.... you can only experience it for yourself, don't base something off of your reading.
A lot if not most of the bad reviews are from those that are either inexperienced mechanically or they don't take the necessary steps to help the engine for the better. Any china 2 stroke kit can be made to be very reliable just depends on the owner. I have over 5k miles on my Chinese kit and have only encountered minor issues. If you like to tinker and tune with things, then the simplicity of the 2 stroke kit is a good option, the china kits will teach you a lot. If your not one for tinkering and you just want to get on and ride then I highly recommend a 4 stroke kit.
