Finished my 520 chain and sprocket upgrade on my 998 tonight and I am looking forward to a test ride tomorrow. Specs as follows:
DID 520 chain
AFAM quick change rear sprocket hub
AFAM 39 tooth steel chain ring
AFAM 14 tooth front sprocket
AEM star drive flange
EVR front sprocket cover

I kept my cush drives as they appeared in pretty good shape. I also picked up a Ducabike aluminum rear sprocket side nut, which looks really nice, but I was nervous about trusting the aluminum and I put the steel nut back on. I will report back on the change the sprocket sizes make.

Got in a nice test ride today. RPM seems to be up by about a thousand in a given gear with the new sprockets. It definitely helped to keep the revs a little higher and smoother. It also enhanced the always awesome freight train pull that I love in the 998.

Whats the best combo for easy wheelies?

Easy wheelies? - Get a 14t front sprocket and bolt an HM1100 to it.
