S2R Rear Sprocket Removal

[Darth Paul]

I'm planning to get the Afam quick change rear sprocket carrier installed on an '07 S2R 800, and I'm considering doing it myself.  I have the PDF version of the '06 workshop manual and I'm looking at the "replacing the rear chain sprocket" page.

The part that's not making sense to me is that at the top of the page it references "Slacken the Chain" and "Remove the rear wheel" before starting the instructions to remove the rear sprocket.  Slacken the chain I get, but is removing the rear wheel necessary?  I thought the whole luxury of the single sided swingarm (and the way the reversible stand works in) is that you can work on the rear wheel OR the rear sprocket based on which side you mount it from, and that the two were pretty independent from each other.

Am I off base here?  Is it possible (or really, correct) to remove the rear sprocket with the wheel still on?

you are correct
you do not need to remove the wheel. you do have to be careful that the axle does not shift in the swingarm when everything is loose.
also be carful not to drop the sprocket into the wheel and scar your wheel.

[NAKID]

They want you to remove the wheel because it is easier to access the back of the bolts holding the sprocket to the carrier. Once they start to loosen, they'll just spin...

[clubhousemotorsports]

when you change the carrier you have the entire part in your hand so no worries of spinning bolts.
with the eccentric in the loose position put the sprocket and carrier in the chain and slide it onto the axle.

where most have issues is if they get the wrong style and do not get the washer correct behind the carrier. if your chain lignment is off when you are done this is probably the problem.

Thanks for all the responses.  So I'll need:

1. rear stand going in wheel side
2. chain adjustment tool
2. afam carrier + sprocket
3. one of those reversible 41/46mm sockets for the axl nut
4. blue loctite for the sprocket nuts
5. torque wrench and enough grunt to get to 115 ft-lbs

Am I missing any parts or tools?  Do I need to worry about grease or anything like that? (bike has 2800 miles on it if it means anything).  I have everything now except for #2 and #3, and I imagine getting #3 will be cheaper than an hour's labor at a mechanic.

Thanks again for all the help here.

You'll need a way or an extra person available to stop the rear wheel from spinning.

I think one of the videos I did covers the single sided swingarm's sprockets...

Ok so I got through most of this today, but now with the new quickchange carrier and the new sprocket it seems a little loose where the cush drives connect to the carrier.  Everything else is torqued to spec.

Instead of trying to describe it poorly, I just made a quick video showing the give.  Is this normal?

If it helps out, mine is exactly the same way. The play is not enough to catch the hub. Bike is a '06 S2R1000 and the carrier is some AFAM-copy (?) of ebay. I would also like to know as I can't remember the OEM sprocket showing any play.

[Darth Paul]

Well whether it's supposed to wiggle like that or not it was finally dry enough today for me to take it out for a quick spin with my new 15/42 configuration which felt totally sweet  (S2R800)

isn't any play there a bad thing though?  i checked mine last night (S4R) and it was tight...

[Darth Paul]

I sent an email to Chris at CA Cycleworks asking him about the wiggle since I imagine he has the most experience with the AFAM carrier (plus that's who I bought it from)

If I get a response I'll post it here, or hopefully he can just chime in on the thread.  If the wiggle is a problem I don't really know what the fix could be other than replacing the stock cush drive dampers with ones that fit the AFAM a little tighter??

[krista]

I believe it would be play along the axle shaft. This is totally normal. For whatever reason, some Ducatis came with a thick washer and others didn't. I'm unsure if Ducati used two different thickness sprockets ... but the in-out play isn't an issue as the carrier will locate to the position for best alignment.

[pennyrobber]

I am running my stock rear sprocket and it has play. I always just assumed that it was done on purpose to allow for proper alignment.

I've got a 996 and an S2R800 in the shop now, both getting AFAM carriers and sprockets.

Both had the OEM style one-piece sprockets.
The 996 had *no* sprocket play whatsoever.
The S2R had the typical looseness.

The SBK and S2R setups are different, I'll be back with pictures.....
