This is an easy process with the right tools. Yes you will need a special tool. RK makes a chain breaker and installation tool wich makes the installtion much easier than using a grinder and punch.

Here is a Motion Pro chain breaker/riveting tool.

 

My 929 came with a Sprocket Specialists rear with 48 teeth, in the split design - meaning the sprocket can be removed without removing the rear wheel. Their site is http://www.sprocketspecialists2.com/SprocketMain.aspx. (The forward sprocket is nothing to remove. Very simple.)
I bought a 41 tooth split sprocket from them and installed it ( thinking that was stock, when actually stock for a 929 is 42) The only complication was that I had to split the difference on the chain adjuster - in other words, when I shortened the chain, there was no "in-between" number of links - I had to move the rear axle back to the "worn" range marker. Not enough room to move it forward, and I didn't mind an extra half inch of wheelbase, anyway.
Also with the reduced diameter sprocket, the chain just kisses the rubber frame guard when I'm not sitting on the bike.
( Anybody notice if your chain does that with a stock 42 tooth? )
Also, buy a high quality swaging tool - you'll be surprised how much force it takes to mushroom the swageable link. Otherwise the process isn't too bad.
ALTHOUGH - the guy in the huge bike shop where I ordered the link looked at me cockeyed and said "Y'know, most guys just replace the swaged link with a clip-style master link." BUT NOOOOOOOOOOOO...... not ME.......I gotta do everything by the BOOK....! ( y'know - the hard way)
Also, have more than one extra link on hand in case you bugger the first one up...... although I managed to get lucky on the first try.

sweet! thanks for all the info. the split sprocket looks nice.

i tried to adjust the chain a bit to make it more rideable until i get the new parts. But i cannot loosen the damn axle nut for the life of me. you guys have air tools or somethin?

 

Gorgeous bike, by the way man - I want to get mine lookin that good by the Spring.
As far as the axle nut, it IS pretty tight - factory torque is 83 foot-pounds. You would never want to use an air tool on something like that anyway.
And the allowable slack on the chain amazes me - 2 inches! The acceptable range is 1.6 to 2.0 inches, but when you set it at 2, it looks like it's gonna fall off.
I'm curious - you said "make it more ridable" - I've never had a worn chain; how is the bike behaving? By that I mean, what are the symptoms you attempting to compensate for by tightening the chain?

 

thank you sixs929,


The symptoms i am having is when i am rideing around, theres a clanking noise comming from the chain. i tried to measure and got
2" & 15/16 of an inch of slack. But the chain doesn't look like it is falling off or anything.

 

I have always kept my chain where you can not move it up or down more than a half inch. It works well for me. It does not loosen up for a couple of months either

 

Yeah I'm exaggerating - the chain would never fall off, but like 929_erion says, seems like a little slack would be OK, 2 inches just seems way too loose.

 

the manual i have is inclear on how to measure the slack. i think i know how but would you tell me just so i am doing it right?

I lubed up the chain real good.. maybe its kinking/binding a bit.
