Depends on whether its fuel injected or carbureted, you didn't specify a year. If its fuel injected then you won't want to lean it anymore than factory because its already pretty high. If you need to alter your A/F mixture on a fuel injected bike you will need to purchase a programmer or fuel controller. If it is carbureted you will need to purchase a jet kit and be ready to spend a lot of time with an A/F gauge and have time to disassemble the carbs every time you want to make a change.
