Quick question: What are the Pros and Cons of Doing a 520 Conversion on an '02 GSX-R1000? Second, the front and rear sprocket teeth count, what does it mean? The more teeth means faster accelaration and top speed, etc?



Thanks,

Mark

520 is lighter chain and narrower. less weight, less rotating mass, bike should run quicker, maybe not that you could tell its quicker, but it is. if your gearing is 17 front(has 17 teeth on it) and 44 back(dont know stock gearing) if u change to a 16 front you will gain some in acceleration but lose some top end mph. 1 tooth difference is front is equivilent to 3 in back. 16,44 would be same as 17/47. one down is front is same as up 3 in back. reverse it for more top end, 18,44 is same as 17, 41. normally is easier and cheaper to replace front sprocket( 20 bucks to 40-50 bucks for rear) hope this helps and diesnt confuse u.

Its really not cheaper. Keep in mind that if you go 520, you will have to change both sprockets due to the stock sprocket teeth are thicker and wont be able to house the narrow 520 chain

i would recommend a 520 conversion, just make sure you don't skimp out on the parts. get quality parts (afam sprockets, rk or d.i.d. chain) and you will be okay. plan on replacing them more often than your stock 530 setup, but the performance gain is nice, especially if you go -1, +2 on your sprockets. go here to get it: www.sprocketcenter.com

Have you guys or anyone here had done a 520 Conversion? Well as far as the sprocket teeth count goes I'm looking for a set up that will give me at least more grunt on top end. For now, my set up includes Yosh Tri-Oval Race Full System, Power Commander 3r, Power Commander Ignition Module and Yosh BMC air filter....

I would not recommend a 520 conversion untill you are very comfortable with the bike as it is. You will get lots more torque on the rear which will increase your lowside, highside, and tankslapper risks.

What I have done that works for me is:

RK VRX Chain(The only 520 with high enough tensil strength for the 1000)
Sprocket Specialist Titan aluminum sprocket.
45 teeth rear and make sure you keep a steel front sprocket.

It's the same set up as Matt Mladin.

By the way.... The 1000 eats parts for breakfast. So if your going to go 520. Plan on replacing chain and sprockets as often as your tires.

Economical wise, how often do I have to change the chain and sprockets once I do the 520 Conversion?

probably every 5k or so miles, depending on how hard you ride. it is all determined by chain stretch and how bad your rear sporcket is worn out. nuk boy brought up a good point and make sure that you keep a steel front sprocket.

nuk boy, where did you get the rk vrx chain? i will be in need of a new set-up soon, and i would like to get one. thanks!

Listen to Nuk Boy. Don't screw around with the 1000cc monster it will bite you in the ass if you start changing crap that doesn't meet specifications, just so you can be a part of the crowd at the coffee cafe.

A quality 520 setup will handle the 1000's power just fine - but like what was already stated, don't skimp on parts. Get the best quality components, especially the chain (RK).

You'll also need to take great care of your chain to ensure long life. You should be lubing every couple hundred miles, and completely washing the chain every 1000 or so. What I mean is don't let the sludge build up - you may be lubing often enough, but lube attracts dirt and the shit builds up quick. Get something like a Grunge Brush and clean everything with an approved cleaner that won't harm the O-rings (Motul Chain Clean). (you should do all this with a stock chain as well) ((it seriously disturbs me when I see the craploads of people rolling around with shitty/scummy/dry/too loose/too tight chains!))

With proper care and quality components, you can actually see 8-10,000 miles out of a 520 conversion on a liter bike.
