I have a 2001 GSXR 750 and it tops out at about 142mph. My friends and I run it sometimes and I can´t keep up. My brother has a stock 2004 600 cbr rr stock and he leaves me. I thought when I got this bike it would top out at about 155 and 170mph. What can I do to get it to open up. It´s all stock right now. Not looking to put a lot of money into it. Just need it to do what it says it does.
Any knowledgeable suggestions would be greatly appreciated. Thanks
