Hello, Nate. Welcome to MBc. Jessie James designs some very distinctive and elegant frames. My personal opinion is that they deserve nothing less than a 4-Stroke engine, such as a Subaru, Honda, or even a Hua Sheng...rather than a 2-Stroke China Girl. But, that is only my opinion...I may be wrong. As far as speed goes, that is mostly a function of gearing. Read the Forum Rules and Stickies at the top of this page. They have a mess of information that will help you. Then, read up on the 2-Stroke and 4-Stroke Forums. Again, welcome to MBc.
