SO as a few of you know, my CB400 was crashed by the mechanic doing the checkup then give it to me..he totaled it and he is fine haha. They gave me a GS500 Naked instead which i thought eww why? after riding it i dont actually mind it has the necessary power i need for what i do.. (long range riding been riding 4-6 hours a day since tuesday - practicing for long rides with netriders haha) But i want to give it a few...nice things Ive been told exhaust maybe but i don't know yet. Any other decent mods...if you can find a list for me..would be amazing..I want to empty out the shit oil they put in it and put some nice oil in it but that's no mod haha. and a new air filter eventually..K&N. Anyone give me a few tips?
