I have a stock 2001 GSX-R 600. I ordered new sprockets for it -1 front \ +2 rear. The problem I am having is that they sent me +3 for the rear instead of +2 . My stock chain is a RK 525 with 110 links. I put them both on and it seemed that the chain was just to short so I went ahead and just put the front one on. Is it possible to put the -1\+3 setup on with a stock chain? If not what chain should I get or if I send the rear sprocket back and get a +2 will that fit with a stock chain? Just trying to see what my options are.
