Icon16 How to change your chain and sprockets

Well, I finally got around to putting on the 520 chain and 16 tooth front and 44 tooth rear sprocket I bought over a year ago from the now defunct Sum of All Parts. They happened to have a tacky looking blue chain and rear sprocket in stock which I HAD to have. (I changed it while listening to Wham!)

The next few posts are a "how to" for those that have never done this sort of thing but want to have a go at it.

Changing chains and sprockets is a fairly easy job to do, especially if you have the proper tools. And if you've never experienced a gearing change like a larger rear sprocket and/or a smaller front sprocket, you don't know what you are missing.

Below is a summary of most of the tools I used. I borrowed my neighbor's impact wrench to get the countershaft nut off since I couldn't budge it with my breaker bar. After I used his, I immediately went out and bought an electric one of my own. And the mini sledge hammer is for smashing stuff when you freak. Usually, having it nearby is enough to make the bike behave.

"How to avoid a shattered sprocket cover" was invaluable when I changed my chain and sprockets on my first SV1000 so I used it again. Also on the SV1000.com site, the service manual for the SV1000 was a great resource too.

After taking the countershaft sprocket cover off, I had a big mess to clean up. You'll notice the copious quantities of gunk in there which is a combination of chain lube, dirt, and debris. I even think I found the entire skeletal remains of a Wooly Mastodon in there. I used hundreds of gallons of WD40 and mrgenius' tooth brush to clean it all out.

Before removing the clutch rod, I taped down the clutch lever so I wouldn't face any issues with the clutch slave cylinder falling out or losing hydraulic pressure.

Ahhh...cleanliness is next to Godliness. But I fear I'm too far gone for cleanliness to help much.

Removing the speed sensor bolt and countershaft sprocket nut requires you to immobilize the rear wheel. And lefty loosey, righty tighty for both the speed sensor bolt and the countershaft sprocket nut. Be very careful trying to unscrew the countershaft sprocket nut with anything but an impact wrench because even with something through the rear wheel to keep it from turning, you can flip up your rear stand. Don't ask me how I know this. Those sumbitches are welded on with super Suzuki red loctite. It must be damn good stuff because the person that wrote the manual had some for "supper".

Some people have used a blow torch on their nuts.

But if you don't want to do that, here's where the impact driver is your friend and life saver.

After I got my nuts off.......... I used a Dremel with a cutting wheel attached (damn, I forgot to put that in the tool pic ) to zip off the end of one of the chain links. Then I used the hand-dandy chain tool (also from Sum of All Parts) to push the pin out. (edit: I recommend getting a beefier chain tool that can handle 520 and 530 chains better. I snapped off a couple of the pins in the particular one I got which seems to be a better tool for bicycle chains, not motorcycle chains. )

Then I put the old chain next to my new one to see how many links I should cut off. Here's where my dumbass got lucky. I should have been much more careful measuring the chain for a linkectomy. I wound up with barely enough chain length to be squeezed on the bike with the new sprockets while maintaining the correct chain slack at full forward adjustment. I mean the chain is exactly in spec! Lucky, lucky, lucky.

Measure, remeasure, then measure again. (Note to self: More teeth on the rear sprocket means you will need more links in your chain. Next time, I'm just going to install the new chain and measure how many links need to come off.)

Then I took the rear wheel off so I could put the pretty blue rear sprocket on.

On goes the 16 tooth front sprocket and the 44 tooth rear. The rear wheel was then reinstalled with the axle reversed. Then the new chain was threaded in. (again with the chain length; LUCKY! LUCKY! LUCKY! )

I attached the chain with a clip-style master link (not recommended) since it was the only one included with the chain and sprocket kit. I have heard the horror stories of these type of links.....but I want to experience one for myself. I put a dab of JB Weld on the clip (pic below) and after I let it cure for a day, I'll go get crazier. And an EK Screw-Type Master Link looks like it might be an even better option for the do-it-yourselfer since no special tools are required for placement of the master link.

Then the countershaft nut and speed sensor bolt go in torqued to spec with red loctite. The axle nut was the final nut in this whole debacle (not including me). The white stuff around the axle adjuster is a little cleanup I missed.

Nice blue job huh?

And yes my speedo will be way off; about 10-15% (maybe even a bit more) off. At 65-70 mph, the bike will probably read about 80 mph. This is a good thing for me.

I like it! Well done, nice write-up.

One question though, thanks to your super-high-res pics, I noticed the rear sprocket has 526A-44 stamped on it, is this a 42 (like you said) or 44 tooth rear sprocket?

Are you a wheelie monster now?

Thanks Rich! Oops! Yes you are right sir! It's been so long ago since I bought the damn thing that I forgot that I had gotten a 44 tooth sprocket.

Wheelies? What are those? I have no idea what you are talking about.

Damn! with those gears, you can rent the bike out as a stump puller....
3-4th gear wheelies anyone?

Yes, Mark!

And after my first ride tomorrow, I am going to start a thread titled "how to change your underwear".

Yeah, probably so. But I've relegated the naked to stunting only.

That's really nice looking!

But I am smug knowing that my black SV and dirty dirty chain already match very nicely thank you.

I too want to reduce the ratio, but undecided on how much. I'm looking forward to hearing how you like the higher gears now (I already know how you are going to like the lower gears ).
