Good eye my young Padowan. Those Splines would worry me more than the Sprocket Teeth because they are fuuucked uuppp. Hopefully the Designers of the bike (them little Jap Fuckers) made sure that the Countershaft Splines are considerably harder that the Sprocket. If not things could be ugly on that bike.
Sorry for the slow reply, but I've been away since I posted this.
Anyway, the countershaft was a good shape - I put the new sporcket on and it was nice and tight - no wiggle for the new one.
Yet another reason to keep buying Hondas!
I decieded that that bolt is never coming out, so I cut the sprocket cover so I could get to the sprocket. Perfect solution? Definitely not. Working solution? Sure
I have owned the bike since new - bought it in Los Angeles and 3 days later rode it 6,000 miles back to PA to break it in :-)
Generally, I wouldn't do this. In fact, I was planning to change the sprocket at about 40K miles or so, until I broke the head off one of the sprocket cover bolts, then broke an EZ-out off when trying to extract said bolt. At that point, I just got dumb and lazy and left it on. I finally decided I've pushed it far enough and resorted to the old hacksaw.
See above - I was, when I bought it, only replacing a sprocket with about 40K miles on it. Now that I have 84K on it, I doubt it would matter WHAT sprocket I put on it, as I don't see it getting more than about 40K more before I get a new bike.
