Dear John,
I found exhausts that will fit the ruckus. I assume this will help the CR try out process because an exhaust will give you many more hps and give you ability to go faster. After all, I know you couldn't ride your old bike stock (SLIPPER CLUTCH IS NOT STOCK HONDA) because you must have parts to go fast. I will help you, but you must do what I say because, after all, you are almost a CR and you can't possible understand RACE FAST.
You may also pay me to make your bike my "B" bike, after all I can't take it off your hands for free because Frankie told me he is already jealous and having another CBR will cause me many problems, but I am willing to do this for you.
Make sure you study very hard for your tests and don't fail because then no one will like you.
You are very welcome.
