no time for a video... but plenty of time to type ***** replies.
maybe jsut type a reply stating out the mods. state the sprocket and the teeth. you used to have chain but went back to belt. explain what how and why. talk of your what ever else you did to achieve your mark. gearing? engine? not general but point out the specifics.
you hve time to type crap. how aobut taking the same time and type something usefull.
