Installing 15t sprocket rant and questions

So I went today to attempt to put this thing on, and my first question: Is it normal for the 15 tooth to be so much thinner than the OEM sprocket? There was a lot of side to side action on the chain once when I got it on.

What I didn't even think about before installing it was that my chain, which I'm pretty sure is the original with 15k on it, is near it's adjustment limit. So once I put the 15t on I didn't have enough space to adjust it to the correct tension


Also, does 40ft/lbs sound correct for the counter sprocket bolt? I found two numbers in the service manual. 40 for the bolt and 80 for the 'drive sprocket nut" which I'm not even sure what that is, mine was a bolt.

If you're at 15k on the original chain and it's at the adjustment limit, I think it may be time for a new chain and both sprockets.

As to the sprocket width, any chance you've ended up with a 520 rather than a 530 sprocket?

I thought about that, I wouldn't know how to tell though. I guess I'd have to ask PegJumpFlyer that's who I bought it from.

Yeah I've been putting it off because the sprockets are in pretty damn good shape, and the chain is still hangin on. Plus I'm still recovering from Chri$tma$.

40 is for the front drive sprocket.
80 is for the nuts that hold the rear wheel sprocket.
They come from the factory manual and are the ones I use.

Aftermarket front sprockets have noticeable end float, and are not axially clamped in place. Don't worry about it.

You have a chain at the end of the stretch indicators and you want to fit a new front sprocket and not change the chain and rear sprocket as well ?
AND put on a front with less teeth that gives less angle of wrap/total tooth contact ?

LOL yeah I know, I really just wanted to see how big the difference was with the 15 on the front. I was planning on trying it out for like 50 miles and switching back. I plan on new chain and sprockets in a few months.

I'm going to sleep better tonight knowing this.

Also, if you're going to change it all, how about a 520 kit ?
Many have done it and I've yet to read a complaint.
15 is a radical change in my mind, and I don't like smaller fronts from an increased chain stress point of view.
I added 2 teeth at the back to get the gearing I was after.
You might want to consider adding 3 or 4 teeth to the rear instead of going to a 15 at the front.

i went with a 15t in the front for awhile... all the hooliganism was fun... but it was asking for trouble.... and i couldnt be nearly as smooth in the turns with the 15... I think i put like 300mi on it then switched back.

+1 When I changed my chain and sprockets, there was more side play on the aftermarket front sprocket. I look at it as a self aligning chain

I've been seeing this for a while on here, but I've also found articles that say they replace sprockets every two chains?? I was wondering about this because my OEM sprockets appear to be in good shape as far as I can tell. Then again Sprocket Center DID chains are only about 30 bucks cheaper than the whole set.

Also what's the difference between all these chains VM2. VX etc.
