Hey all, I got a couple questions.

1. when i run it out of gas and look in the tank (pull up the lid) it is smoky. is this normal?
2. what other than shocks/springs should i upgrade. Im not concerned w/ "bling" just want durability. Best brand?
3. tuning ideas? i still coat the body w/fuel from the exhaust after a couple tanks.
4. What else should i know?

Any ideas would be great....
