I ordered if from the dealer. It's cheap enough where I wasn't concerned to find the best possible deal. I figured I've tried on enough things there and gone online to order it, that I could spend a little money their way.

Ok, I finally got the sprocket on! It was a lot easier than I expected it to me. I am not really mechanically inclined, but I like to tinker. I am sure anyone could do this. I think this is easier than adjusting the chain - if you can do that, you can certainly do this. I installed my new ProGrip grips the same day and even that was more of a pain than this was.    After I took it for a ride to test it out to make sure I didn't screw anything up too badly, I was very impressed. It is noticable. Still no rocket of course but I could definitely feel the improvement. Trust me and everyone else when they say this is an awesome mod to do 

Here is my recap.

My bike is a 2004 GS500F.

I used the SUNNEX 33315 15 tooth sprocket. It was $16.32 plus tax from the Suzuki dealer:





To replace the 16 tooth stock sprocket with the 15 tooth sprocket, I basically followed the step by step instructions from the Haynes repair manual. I happen to have one for the older 89-97 GS500E model, but it still worked just fine. In summary:

1. Unscrew the pinch bolt on the gear shift lever and remove it. Take note where it is so you can put it on exactly the way you took it off. Remove the 5 bolts that hold the sprocket cover onto the crankcase. I used an 8mm socket for this. Take note that two of the bolts are short, the other 3 are long. Lay them out in order so you know where each one goes back to properly.



2. Remove the circlip that holds the sprocket on the shaft. This was probably the hardest part because I couldn't find my needlenose pliers so I had to be creative; I used my finger, a knife, and a screw driver. Tip: Just go get some damn needle nose pliers. Set the circlip aside and don't lose or destroy it so you can reuse it.



3. Slide the sprocket (with chain on it) off the shaft. You might need to loosen the chain to get it off, but I didn't have to.

4. Take the old sprocket off the chain and put the new one in it's place. This is pretty obvious. Put the circlip back on and make sure it is properly seated in it's groove.



5. Reinstall the sprocket cover, the gear change lever, etc. Basically just install everything back in the reverse order you took it off.

6. I had to re-adjust my chain, I ended up with some extra slack. So be sure to check and adjust your chain. You can find out how to do this by going here .

Like I said, this was very much worth doing. While I had the cover off, I did a clean out similar to how RedShift had previously posted directions for. There was a lot of gunky sludge built up in there so I cleaned all that out while I was in there. I even used a little bit of Engine Degreaser to make the inside of the case purrty.

So what sort of effect does the new sprocket have? Does it mess with your RPM / gear / speed ratio?
I noticed some changes when I went with a taller rear tire, I'm wondering if the different sized gear has a similar effect.

It has the opposite effect from a taller rear tire.   You get a little more torque to the rear tire but you will be running higher rpms in all gears. Also, theoretically, more wear on the smaller sprocket.

The OEM sprocket is the best compromise.

If the bike doesn't carry much weight then I wouldn't bother changing.  If you carry a passenger and/or other heavy stuff then 15 teeth helps with get up and go but at highway speed you'll be looking for a seventh gear.

So a 15T sprocket combined with a taller tire should even out?
Because I notice that in 6th I have trouble getting the RPM up and usualy have to downshift. The crawl from 90 to 100mph is really slow.
So would it make sense for me to do this mod. Although, I really dont carry much weight, and I only weigh 140lbs.
