I am looking for a conversion kit for my 2001.
Any ideas as to where to get one, there are so many chain shapes and sizes I am a little confused as to what to get. ???
Does it make it peppier at take like they claim???
would like some feedback. thanks!

A typical "conversion" is the 520.

The biggest thing to keep in mind is that the countershaft sprocket, rear sprocket, and chain need to be the same pitch (ie 525 (stock), 520, 530 etc.)

520 conversions give a lighter, higher strength setup, however given the horsepower of our bikes, not necessary.

Hope this helps some.

520 is lighter, yet weaker than a 525.

A 520 chain is more then enough for the SV.

I buy most of my stuff from parts411.com

I'm running AFAM sprockets front and rear w/ an EK 520-VM X-Ring.

I'm really happy with it, and it will be the same setup going back on when this one wears out.

So far 6k miles and looks like it should do another 6k easy.

Even when compared to stock components? News to me.

www.sprocketcenter.com Go pick up one of the 520 kits from there.

As for 520 being weaker...eh...I believe crappy chains, regardless of size, are weaker.

Thats kinda what I was getting at I guess... Oh well, 520 for me.

There´s chain pitch (e.g. 520, 525...) and gear ratio to be kept in mind.
As for the latter, I went from the standard 15:44 (for the S) via 15:46 (for one chain life) up to 15:47 and am quite happy with it.

15:47 is very, very close to the 14:44 I was running, and the 16:50 520 that will be next... GREAT RATIO, unless you do mucho highway.

Going one tooth down in the front is very close to doing 3 teeth up in the rear...

Going down teeth in the front and up in the rear will result in quicker acceleration, but will also have an effect on RPMs while cruising and top end speed (for what it matters).

Keeping a 15 or even going to a 16T tooth front sprocket and making your changes to the rear is a smarter move as the stress it spread over more teeth resulting in better wear characteristics.

If you do 16T, you can also use a stock GSXR countershaft sprocket which still has the rubber bushing on it.

so going smaller (to a 520) is a weaker chain?? now is that for aggressive riding it is weaker?? because I am not pushing my SV at all.
And I should get only a rear sprocket change instead of both??

520 is plenty strong for an SV. Kawi 600RR came with them stock, they make just a bit more power ;)

If you change to 520, you must replace all components, as your stock size is 525.

My $0.02....

If you decide to convert your chain & sprockets I'd recommend using steel sprockets for the street. They tend to wear much slower than aluminum and they are cheaper to boot! I used JT sprockets - not the easiest to find, but worthwhile as they are OEM sprocket manufacturers. I did the whole conversion for $130 including an RK gold chain (ebay).

Also, if you use a clip on master link, be careful when installing the retainer clip - when done, use a dollop of sillicone to ensure the clip will stay put - works perfectly!

Good luck,

not true, 520 chains are generaly rated for same strength as 525
difference is the weight savings isn't as much in the chain as going to aluminum sprockets, if the sprockets wear faster, the chain will wear faster, sprockets are the weak component of the 520 conversion

So they why do the chain maunf. rate the chains only up to X HP?

Cheap ally sprockets will war like they'e made of toffee... But Renthal ones don't, they're hard anodised and last, I'd say, about 2/3 to 3/4 as long as steel. But then again, my bike's making about 15% more power than it did on the stock sprocket which is probably accelerating wear. if you want to a 520 chain and used a steel sprocket, I'm 100% sure that'd be heavier that a 525 chain and a good ally rear sprocket.

Ally is much, much more vulnerable to a worn chain though- you'd need to be on top of your chain maintenance because a sticky chain can tear the softer sprocket up.

How about those Stealth sprockets, the ones with the steel teeth and ally carrier? Good idea, that...

I found my kit, 520, -1/+1 (14/46) on ebay, for $140 shipped. Love it. My accel is so much better all the way around, and the one-two shift is incredible. Def reommend this mod. Makes it a whole new bike.

i use to own a '02 svs blue, and i installed a stock size front (new) with a d.i.d 525 chain, and went up three in the rear...and that moffugga added alot more acceleration. and i road that thing from va all the way to boston and back, and sc and back...but as for the durability, it was an aluminum rear sprocket from vortex which lasted me around 4000miles....sooooo...
now i have a '06 sv naked, and am about to replace the rear stock size 45, for a 48 from sprocket specialist...and fron what i hear, they are better and last longer!
