lets talk chains and sprockets
 

My chain is stretched to the max and I need to get a new chain and sprockets Id assume. I want to do a -1 in the front/+2 in the rear for the sprockets and someone was telling me to do a 525 conversion. Is that even possible on a 2001 GSXR 750. I was also told to do a "X Ring" chain because of durability.

As far as keeping my speedo to read correctly what do I need there.

Where is a good/inexpensive vendor to get all this stuff at.

Renthal Sprockets. DID or Regina chain. I went with x-ring. Just check around on the internet for prices. A decent chain and sprocket set isn't cheap. About the 525, no clue.

Instead of what someone told you, how about figuring it out for yourself. Find a conversion table online. The -1, +2 is about a 10 percent change. That means if your top speed was 150, your new top speed is 135. If your cruising rpm was 5,000, your new cruising rpm for the same speed is 5,500. If your mpg was 40, your new one will be 36. Most speedos read 10 percent more right from the factory. So 60 on the dial is really 54 mph. Another 10 percent would be 48 mph when the speedo reads 60. And you think your Gixxer could loop it before, with the -1, +2, well, I don't have to tell you.

Do like T said but go 520. Many guys are running 520's on way more powerfull bikes than the 750

The 525 is stronger than a 520 but will be more $$$

But the 520 is lighter and you have less rotational mass in the drivetrain which means less drivetrain power loss which means more power to the rear wheel.

Everyone recommended for me to get a 530 on my modded R1. The 520 should be fine though.

I just got off the phone with a local bike shop and they said the stock chain is a 525. So I will just stick with a 525.... Is there anything I can get that will calibrate the speedo to read correctly.
