Hello. I am new here, and I love your site and I love engines! The reason I came here was to see if any of you could recommend a kit for me to use. I want something relatively cheap. It does not matter 2 stroke or 4 stroke. Thank you. Edit: What do you all think of www.kingsmotorbikes.com? Edit again: After much consideration and searching on the forums, I feel that www.thatsdax.com will be my best option for a conveniently priced motor bicycle. Any comments or concerns from you guys about this website? Again, many thanks for your help and the information I have been able to find.
