The additional complexity & thus maintenance of a jackshaft is often accepted by builders not for a top speed gain, but for improved acceleration and lowered RPM at cruise speeds, making for a more comfortable & efficient ride...[/url]
I see. I WAS under the misconception that all I needed was gears. I returned to a prior thread post by HuffyDavidson and noticed that he did indeed state he is running an advanced motor with his shiftkit.
Thank you for clearing that up.
I will definitely stick to my stock China Girl setup for this build this year.
I may get by without incident, we'll see.
I think I might order a smaller rear sprocket to bring with me.
On ebay I'm seeing 32, 36, 39 and 41 tooth sprockets mainly by a seller who happens to be in Puerto Rico which is very convenient. I noticed most of these do not have a convex to them.
Any input would be appreciated.
