I recently purchased a used bicycle. They did not have the owners manual, or any information for me really. The serial/model number is 66rz 0054. There was a sticker on the motor and it has some more information if you would like me to post that as well. I am curious to know what the proper fuel mixture is? Also if anyone knows if there is an owners manual available somewhere online or for purchase? Thanks in advance if anyone can help **Please move this post to the correct thread. Thanks.
