So it looks like I"m getting some new (used) sprockets.  I have absolutely no idea how to change them, anyone want to help me out?

All you need to do is remove the rear wheel and unbolt the sprocket (15mm socket) and for the front the sprocket is held on by a plate that bolts onto the sprocket (8mm socket) so it just slides off when the plate is off.  It's an easier process on ducati's than other brands because of the front plate deal.  1/2 hour job [bacon]

Easy enough job to do yourself. Just make sure you align the rear wheel properly when you get everything back together.

Here are some torque values if you don't already have them.

And an article on aligning the rear wheel.

I don't have a torque wrench.....

The previous owner made some plates that sit on the axle to align it, so that's not an issue.

You can pick up a torque wrench from your local hardware store. No need to spend exorbitant amounts of money on a micrometer wrench, just pick yourself up a beam style torque wrench. Which ever one you decide to get though, a torque wrench is a must.

I strongly recommend picking up a torque wrench.  They are indispensable for motorcycle maintenance, particularly sensitive things like axle bolts.

I changed out my front sprocket in 20 minutes, and I am slow.

Obviously, once done, you need to adjust the chain, too.

A torque wrench like this is fairly cheap and works fine.

To align your rear wheel, you should pick up a chain alignment tool.
They sell them at Midwest Cycle on Nicollet and 43rd. I'm just sending this link for reference.

Two wheels good. Four wheels bad.

this is turning out to not be a super cheap mod.

$25 for the sprockets
$25 for a torque wrench
$25 for a chain alignment tool

That's triple what I had intended to pay.

So, do I really need a chain alignment tool?  can't I just eyeball it, and use the little things the PO made? 

And can I just borrow somebodies torque wrench?

atomic410

don't use the marks on the swingarm they don't match up; at least mine don't.  They will get you close though. a flat piece of steal can help you eyeball it. and you are getting away cheep.  Last season I wen't through $100 just in sprockets racing. [bacon]

You bought the wrong kind of "toy" if you think things are gonna be cheap. Wait till you have to buy a new chain or a new set of tires, both things you don't ever buy used. Or when you have to do a tune up, those aren't cheap either. I paid $80 for just my rear sprocket and I thought I was getting a deal!

Well I haven't spent more than $100 on her yet, and half of that was for oil and a filter.

All of my mods have been do-it-yourself jobs.  Taillight made with LEDs I had laying around from another project.  Tail chop.  License plate bracket made from pieces left over from the tail chop.  Removed vent pods and emissions crap.  chopping stock cans I got from the big Schwanger for $40.  blinkers I got online for $9/pair.

Oh shoot, I forgot about the powdercoated rearsets for $50. make it $150 I've spent.

I am one cheap bastard.

And it's all for naught, the guy sold the sprockets to somebody a little quicker with the paypal.
