Welcome yamaha man... and congratulations on your new bike.
I assume you are a young man....because many of us here would interpret your "sick" as disgusting!!

(which the JTR is not).... but I have teenage sons so I know what you mean
Please be prepared for two things.....
1. When you've been riding the rocks and sections for a while your bike might look a bit battered... but that's the nature of the sport and if it doesn't your not trying hard enough
2. Any extra things you bolt on will effect your balance and geometry and when you fully appreciate that you will remove those extras anyway.
If you wanna get good learn some stationary balancing, watch some training DVD's, then find someone that's good to ride with..... then practice. practice.practice!!
Best of balance.
