I have a 2002 954rr with stock chain and gear ratio. I want to do 520 and -1/+2 with either a DID chain or a different high quality chain. No one I see has a good kit, do I need to piece my own kit together or what? And is Moto-heaven the best place online to buy from?

 

Did you try bikebandit.com?

You might have to piece together your own set. -1/+2 isn't too crazy that you will need to order a custom length chain, so you have many options.
