Re: rear sprocket and chain (cintas)
Well, if it's a 748 like mine I went from 14/38 to 14/40 and it really helped wake up the bike. I did it all at once, so I can't isolate what did what, but that sprocket change, a light flywheel and the Marchesinis (duh) really made it into a new bike.
(edit: If the setup is like mine, you will use the same length chain going from the 38 to the 40. Also, I believe that it's best to replace the chain if you change the sprockets).
Anyway, the bike pulls much harder now. If I could do wheelies, the bike would probably comply with ease now. But I can't do wheelies .......
Like Phil said, take a look at Section 8 and they'll take care of you. (right after you open the box and it's actually a 60 tooth rear and you spent all day working in the driveway in 135 deg. heat)
(Now, nick, that's just a joke. Don't worry, this will all be over soon and we'll look back on this and laugh.
