Not bad. They look normal to me, but I'm a newbie at this yet. I asked my dealer's service guy yesterday how to do a check. He told me the best way to read 'em is to run the bike right up to the red line in 2nd or 3rd gear, then grab the clutch, dump the throttle and hit the kill switch at the same time (well maybe the clutch a split second sooner). BTW red line in 3rd gear is over 70mph for my 05 Speedy. Then pull off the road grab your trusty socket wrench, pull 'em and have a look. Mine looked good, maybe just a little lean.
