Re: A Warning to those looking in getting a Chinese engine kit
I apologize for my wise-crack early on, but you will have to learn some basic mechanical skills in order to make this work! It's not the Plug-and-play installation that many advertizers claim!
I know: Most of the vendors will tell you, "In three hours you'll be done with the installation". This is a stretch of the truth to say the least!
These bikes are a lot of fun...I hate to see someone toss in the towel over one bad experience.
As joe said...you may have gotten a bad engine.
If you start over and ask questions prior to moving forward you'll have a much better experience with the whole thing. Expect to spend a few days getting the thing together properly. There are modifications that need to be made prior to even installing the kit!!!
There is no such thing as luck when it comes to mechanical things...just calculated results!
